摘要：

通过对下降法生长的全尺寸钨酸铅（ＰｂＷＯ４）晶体沿长轴方向不同点的透过率和光产额的测量、分段晶体的透过率和光产额的测量，研究了钨酸铅晶体的发光均匀性及其影响因素．结果表明：钨酸铅晶体发光均匀性主要由生长后期的钨酸铅晶体质量所决定，采用晶种为大头的加工取向有利于提高钨酸铅晶体的发光均匀性．

关键词: PbWO4晶体, 透过光谱, 光产额, 发光均匀性

Abstract: The uniformity of PbWO4 crystals grown by the Bridgman method was investigated by the measurements of transmission and light yield for full-size crystals and the different parts of ingot.The results show that the crystal quality in the later growth period is the main factor mfluencing the uniformity, and a favorable geometric shape can improve the uniformity of PbWO4.

Key words: PbWO4 crystals, transmission spectra, light yield, uniformity
