本文首次研究了euga2s4化学计量化合物的光致发光性质。出现在510 ~ 620nm区域的发射具有很高的量子效率值，在低温下达到100%。发射的特征与CaGa 2s4: Eu相似，可以认为是由于Eu离子的声子端跃迁。根据实测的发光数据，讨论了构建独特的高增益可调谐激光器的可行性。
Photoluminescence properties of the stoichiometric compound of EuGa 2 S 4 has been investigated for the first time. The emission appearing in the region of 510–620 nm has a high quantum efficiency value reaching 100% at low temperatures. The characteristics of the emission are similar to those of CaGa 2 S 4: Eu, and can be considered to be due to phonon-terminated transition of the Eu ion. Based on the measured luminescence data, construction feasibility of unique high gain tunable lasers is discussed.
