采用斜射式激发样品光路结构,设计了应用于测试时间分辨同体表面荧光光谱系统.利用该系统研究了氧化锌薄膜在355 nm激光脉冲激发下的时间分辨固体表面荧光光谱.结果表明,该系统能够实现测量时间分辨固体表面荧光光谱,并由此测量了样品的固体表面荧光寿命.该系统结构简单可靠,灵敏度高,响应速度快.%A system has been designed with the oblique incidence optical structure to measure the time-resolved solid-surface fluorescence spectra- The system was applied to measure the time-resolved solid-surface fluorescence spectra of ZnO films excited by 355 nm nanosecond laser pulses. The results show that the system can measure the time-resolved spectra of solid surface fluorescence, from which the fluorescence lifetime can be obtained. The system is reliable with simple optical structure, high sensitivity, and high-speed response.
