Ｔｌ＿３ＡｓＳｅ＿３是一种性能优良的红外非线性和声光材料。我们用元素直接化合的方法制备了多晶料，利用Ｂｒｉｄｇｍａｎ方法生长出了Ｔｌ＿３Ａｓｓｅ＿３晶体并对该晶体进行了初步测试。报道了我们的生长方法及有关结果。
Tl_3AsSe_3 is an excellent infrared non-linear and acousto-optic materials. We prepared the polycrystalline material by the direct chemical combination of elements. The crystal of Tl_3Asse_3 was grown by Bridgman method and the crystal was tested. Reported our growth method and related results.
