首次报道了PbWO4:Sb的光谱特性,包括透射谱和Xe灯光源激发的发射谱与激发谱.掺Sb具有增强绿光带、抑制红光带并大幅度提高光产额的效果.通过与空气退火PWO发光的比较,对绿光带的起因、Sb掺杂的作用也进行了简要的讨论.
The spectral characteristics of PbWO4: Sb were reported for the first time, including the emission spectrum and the excitation spectrum excited by the transmission spectrum and Xe lamp. Sb doped with enhanced green band, inhibit the red band and greatly improve the effect of light output. Through the comparison with the air-annealed PWO luminescence, the cause of the green band and the effect of Sb doping are also briefly discussed.
