| 1 | One-pot synthesis and optical properties of In- and Sn-doped ZnO nanoparticles显示文摘Colloidal indium-doped zinc oxide(IZO) and tin-doped zinc oxide(ZTO) nanoparticles were successfully prepared in organic solution,with metal acetylacetonate as the precursor and oleylamine as the solvent. The crystal and optical properties were characterized by X-ray diffraction,UV?visible spectrophotometry,and fluorescence spectroscopy,respectively; the surface and structure morphologies were observed by scanning electron microscopy and transmission electron microscopy. The XRD patterns of the IZO and ZTO nanoparticles all exhibited similar diffraction peaks consistent with the standard XRD pattern of Zn O,although the diffraction peaks of the IZO and ZTO nanoparticles were slightly shifted with increasing dopant concentration. With increasing dopant concentration,the fluorescent emission peaks of the IZO nanoparticles exhibited an obvious red shift because of the difference in atomic radii of indium and zinc,whereas those of the ZTO nanoparticles exhibited almost no shift because of the similarity in atomic radii of tin and zinc. Furthermore,the sizes of the IZO and ZTO nanoparticles distributed in the ranges 20–40 and 20–25 nm,respectively,which is attributed to the difference in ionic radii of indium and tin. | Li-ping Wang Fu Zhang Shuai Chen Zi-heng Bai | 2017 | International Journal of Minerals,Metallurgy and Materials2017，24，4： | 0 |

| 3 | Optimization of organic light emitting diode for HAT-CN based nano-structured device by study of injection characteristics at anode/organic interface显示文摘To increase the current density of the hole only device, 1, 4, 5, 8, 9, 11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) material has been inserted in the device at the indium tin oxide (ITO)/organic interface. Since HATCN molecule can withdraw electrons, it can alter electronic properties of the electrodes and hence inserted between the organic/metal interfaces. This paper deals with the optimization of the thickness of organic-metal layers to enhance the efficiency. Also, efforts have been made to increase the current density and reduce the operating voltage of the device. The material 2, 7-bis [N, N-bis (4- methoxy-phenyl) amino]-9, 9-spirobifluorene (Meo-Spiro-TPD) is used to simulate the hole only device because it is a thermally stable hole transport material. Simulated results shows that better current density values can be achieved compared to fabricated one by optimizing the organic metal layer thickness. The best optimized layer thickness of 22 nm for Alq3, 25 nm for *CBP doped with Ir(ppy)3, 9 nm for Meo-Spiro TPD and 4 nm for HAT-CN which results in current density of 0.12 A/cm2 with a reduction in operating voltage by approximately 2 V. | Neha JAIN O.

| 4 | Preparation of the In_2O_23·Sn Films by MO-CVD Technique显示文摘Introduction In2O3·Sn films have high transparency(>95%) within the visible spectral region, low resistivity(10-2—10-4 ohm·cm) at room temperature and superior thermal stability. These films have been applied to solar cells, electronics and photoelectronics fields. In recent years, organometallic-CVD method has emerged as a successful alternate to the physical methods and general CVD for the growth of these films.

| 6 | Influence of white light illumination on the performance of a-IGZO thin film transistor under positive gate-bias stress显示文摘The influence of white light illumination on the stability of an amorphous In GaZnO thin film transistor is investigated in this work. Under prolonged positive gate bias stress, the device illuminated by white light exhibits smaller positive threshold voltage shift than the device stressed under dark. There are simultaneous degradations of field-effect mobility for both stressed devices, which follows a similar trend to that of the threshold voltage shift. The reduced threshold voltage shift under illumination is explained by a competition between bias-induced interface carrier trapping effect and photon-induced carrier detrapping effect. It is further found that white light illumination could even excite and release trapped carriers originally exiting at the device interface before positive gate bias stress, so that the threshold voltage could recover to an even lower value than that in an equilibrium state. The effect of photo-excitation of oxygen vacancies within the a-IGZO film is also discussed. | 汤兰凤 于广 陆海 武辰飞 钱慧敏 周东 张荣 郑有炓 黄晓明 | 2015 | Chinese Physics B2015，24，8： | 0 |
| 7 | Lack of nano size effect on electrochemistry of dopamine at a gold nanoparticle modified indium tin oxide electrode显示文摘Nanometer sized materials have been shown to possess excellent chemical and electrochemical catalytic properties.In this work,a gold nanoparticle (AuNP) modified indium tin oxide (ITO) electrode was employed for investigating its electro-catalytic property.AuNP was deposited on the 3-aminopropyltriethoxysilane (APTES) modified ITO electrode by self-assembly,and was characterized by scanning electron microscopy and cyclic voltammetry.Although the electrochemical reaction of dopamine was very sluggish on the ITO/APTES electrode,it was significantly enhanced after AuNP deposition.The cyclic voltammogram exhibited apparent dependence on the surface coverage of 11 nm AuNPs,which could be rationalized by different modes of mass diffusion.Among the different sizes of AuNP investigated,the lowest anodic peak potential was observed on 11 nm AuNP.However,the potential was still about 50 mV more positive than that obtained on a bulk gold electrode of similar geometry.It is therefore concluded that there is no nanometer size effect of AuNP modified ITO on the electrochemistry of dopamine. | HUANG RongFu & GUO Liang-Hong State Key Laboratory of Environmental Chemistry and Ecotoxicology Research Center for Eco-environmental Sciences,Chinese Academy of Sciences,Beijing 100085,China | 2010 | Science China Chemistry2010，53，8： | 0 |
