| 2 | Cathodoluminescence of diamond synthesized from silicon-carbide显示文摘As a wide energy gap semiconductor, diamond is expected to play a role in UV light-emitting diode or laser. However, the impurities and vacancies in diamond exert a great influence on optical properties of the crystals. It is important, therefore, to study the relation between impurities and the optical properties, and furthermore, to study the control of the impurities. | 洪时明 KANDA Hisao 芶立 | 1996 | Chinese Science Bulletin1996，41，3： | 2 |
