Abstract
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.
