| 摘 要： | 通过脉冲激光沉积（PLD）技术在多孔硅（PS）衬底上制备了ZnS薄膜。用光致发光（PL）的方法观察到白光发射，这个白光是由ZnS薄膜的蓝、绿光和PS的红光叠加形成的。白光光致发光谱是一个从450nm 到700nm的较强的可见光宽谱带。同时研究了激发波长、ZnS薄膜的生长温度、PS的孔隙率和退火温度对ZnS/PS光致发光谱的影响。

| Abstract: | ZnS films were deposited on porous Si (PS) substrates using a pulsed laser deposition (PLD) technique. White light emission is observed in photoluminescence (PL) spectra, and the white light is the combination of blue and green emission from ZnS and red emission from PS. The white PL spectra are broad, intense in a visible band ranging from 450 to 700 nm. The effects of the excitation wavelength, growth temperature of ZnS films, PS porosity and annealing temperature on the PL spectra of ZnS/PS were also investigated. |
