| 摘 要： | 本文考虑玻璃中能级间距的分布以及自旋-轨道耦合引起的E和T状态混杂,计算了Cr发射谱线的线形。用此模型计算得到的结果与实验得到的三价Cr掺杂的铝红柱石(mullite)陶瓷和硅酸盐玻璃以及四价Cr掺杂的Mg-Ca-Ba铝酸盐玻璃的发射光谱符合得很好。

| Abstract: | n this paper we present a model which accounts for the emission lineshapes observed in chromium doped disordered systems.The model takes into consideration both the site distribution and the admixture of the E and T states through spin-orbit coupling.The calculated lineshapes are in good agreement with those observed in Cr3+ doped mullit ceramics,Cr3+ doped silicate glass and Cr4+ doped MgCaBa aluminate glass. |
