【摘要】用光致发光谱（ＰＬ）方法研究不同温度下Ｚｎ１－ｘＭｎｘＳｅ中Ｍｎ＋＋内部３ｄ壳层电子４Ｔ１（４Ｇ）→６Ａ１（６Ｓ）跃迁的发光特性．实验结果表明，随着温度的升高，Ｚｎ１－ｘＭｎｘＳｅ（ｘ＝０．１１，０．１７）的发光谱的发光峰位置产生蓝移，这一变化规律主要是由于温度升高引起晶格膨胀，从而削弱配位场效应所造成的更多还原

【Abstract】 The 4 T 1( 4G)→ 6A 1( 6S) emission of Mn 2+ intra d transition has been studied by photoluminescence at different temperatures ( T =10 K, 100 K,200 K, 300 K). It is shown that the emission band shifts to blue as temperature increases. Such blue shift is due to the thermal expansion of the lattice, which weakens the effect of ligand field acting on Mn 2+ ions.更多还原
