| 摘 要： | 以磷酸三乙酯、硝酸铝和正硅酸乙酯为原料，通过它们的水解制备了ｘＡｌ２Ｏ３·ｘＰ２Ｏ5·１００ＳｉＯ２（ｘ＝０．２５～３）凝胶．在６００℃对凝胶进行热处理，使其中的有机基团炭化，从而制备出了镶嵌有碳纳米颗粒的ｘＡｌ２Ｏ３·ｘＰ２Ｏ５·１００ＳｉＯ２（ｘ＝０．２５，０．５）凝胶玻璃．在室温下以５３２ｎｍ激光（Ｎｄ：ＹＡＧ）激发，在 ６３０ｎｍ处有一强的发光峰，该发光现象是由镶嵌在凝胶玻璃中的纳米碳颗粒产生的．

| Abstract: | C-nanoparticles embedded xAl2O3*xP2O5*100SiO2 (x=0.25 or 0.5) gel-glasses were prepared by a sol-gel process. The gels synthesized through hydrolysis of PO(OC2H5)3, Al(NO3)3*
9H2O and Si(OC2H5)4, were heated at 600C for 10h, in which－OC2H5 were carbonized to precipitate nanosized C particles. Glasses doped with C nanoparticles showed a strong room-temperature 妏hotoluminescence with a peak at 630nm under 532nm Nd:YAG laser excitation. The photoluminescence spectra were caused by C nanoparticles embedded gel-glasses. |
