摘要：
The decay time of the blue luminescence at room temperature in n-type ZnSe grown by metalorganic chemical vapor deposition has been measured, using a mode-locked laser as excitation source and a streak camera for detection. Over an uncompensated donor concentration range 10(17)-10(18) cm-3 the decay time is of the order of 100 ps. The short time is a result of strong nonradiative recombination: it is argued that the concentration of Hall-Shockley-Read recombination centers is high.
