摘　　要：用Ｃｚｏｃｈｒａｌｓｋｉ法生长了掺镁ＰｂＷＯ４晶体，测试了Ｍｇ：ＰｂＷＯ４晶体的透射光谱、激发发射光谱、发光效率和衰减时间。Ｍｇ：ＰｂＷＯ４晶体的透过率和发光效率高于Ｐｂ－ＷＯ４晶体。Magnesium doped PbWO 4 crystals were grown by Czochralski method. Their infrared transmission spectrum, emission spectrum, luminous efficiency and decay time were measured. Transmissivity and luminous efficiency of Mg:PbWO 4 crystals are higher than that of PbWO 4 crystals.

关 键 词：掺镁 晶体生长 发光效率 衰减时间 钨酸铅
