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.

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 influencing the uniformity,and a favorable geometric shape can improve the uniformity of PbWO4.
