摘要：

Temperature dependences of luminescence for the free exciton and the Te-induced self-trapped exciton in ZnSe1-xTex (x approximately 0.005) are studied. The intensity of the free-exciton line increases up to 50 K with the temperature and decreases above that temperature, while that of the self-trapped broadband monotonically decreases. This phenomenon is quantitatively analyzed in the framework of a kinetic model and discussed by using a configurational coordinate diagram.
