摘要
金属有机化学气相淀积用于制备掺Er的In1xGaxP外延层。低温下,研究了温度与光致发光性质的关系作为合金成分的函数,其中合金成分为x=0-0.98,发现所有掺Er的In1-xGaxP外延层都在0.801eV处有一上强光致发光峰,与合金成分无关,295K时观测到In0.52Ga0.48P样品的Er^3+离子的光致发光特征峰,发光强度明显降低。
he Er-doped In1-x GaxP layers have been prepared by atmospheric pressure metallorganic chemical vapor deposition.Temperature-dependent photoluminescent propeties were studied as a function of alloy composition for x=0~0.98.All the Er-doped In1-x GaxP layers exhibited strong PL emission at 0.801eV which was independent of the alloy composition.For In0.48 Ga0.52P alloy Er3+-related luminescence is observed at 295K.
