| 摘 要： | 本文对用溶胶-凝胶方法制备的xAlP/100SiO2凝胶玻璃的光致发光进行了研究,表明585nm附近的发光是凝胶玻璃中的AlP纳米晶粒表面态和缺陷复合发光.发光峰位与AlP的参杂量无关,但发光峰的强度随x的增加而减弱;另外与H2的反应时间越长,发光强度减弱.

| Abstract: | Photoluminescence spectra excited by 532nm laser of AlP/SiO2 nanocrystallites prepared by sol－gel techniques at room temperature is studied.The PL spectra (550～700nm) is originated from recombination of surface state and defect.The maximum location of PL spectra has no relation to the size of AlP nanocrystallites,but the intensity of PL spectra is decreased by increasing of the AlP contents.The reaction time with H2 has influrence on the photoluminescence. |
