1Characterization of Vacuum Ultraviolet (VUV) Radiation for the Development of a Fluorescent Lamp显示文摘A negative unipolar pulsed voltage is applied to study internal electrical parametersof the xenon filled dielectric barrier discharge(DBD)sources.The VUV radiation emitted fromthese sources is characterized by means of the photoluminescence intensity of the red phosphorpellet.The red phosphor converts the VUV radiation into visible radiation and the emissionspectra include a peak at 619.56 nm.The emission characteristics of the red phosphor are analyzedin terms of the pressure-distance(pd),rise time and frequency of the pulsed voltage waveform.The emission intensity measured at different operational conditions confirms that the formationand decay of the xenon excimer,Xe2*,increase with the increase in reduced electric field,E/N.After exceeding certain limits of E/N,the intensity of Xe2* decreases rapidly.Hasina KHATUN A.K.SHARMA P.K.BARHAI 2011Plasma Science and Technology2011,13,4:0
