Photoluminescence Properties and Preparation of Nanosized Carbon Particles Embedded Gel-Glass

Abstract

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 600℃ for 10h, in which -- OC₂H₅ were carbonized to precipitate nanosized C particles. Glasses doped with C nanoparticles showed a strong roomtemperature photoluminescence with a peak at 630nm under 532nm Nd:YAG laser excitation. The photoluminescence spectra were caused by C nanoparticles embedded gel-glasses.

Key words: sol-gel process, C/xAl₂O₃·xP₂O₃·100SiO₂ （, C-nanoparticles, photoluminescence properties
