It is demonstrated that the red phosphorescence is resulted from the conversion of Eu2+ activated blue phosphorescence through persistence energy transfer from Eu2+ to Cr3+. The excitation spectra of the 694 nm emission exhibit strong f-d band of Eu 2+  indicating the existence of the energy transfer. The dependence of lifetimes and intensities of the red and blue emissions on Cr3+ concentrations are studied. The intensity ratio of the red to blue emission bands obtained from photoluminescence spectra is in good agreement with that obtained from fluorescence lifetime measurements. The decay curves of the red phosphorescence at 694nm are also studied.   Kinetics study on melt grafting copolymerization of LLDPE with acid monomers using reactive extrusion method 期刊论文  OAI收割 journal of applied polymer science, 2006, 卷号: 101, 期号: 6, 页码: 4301-4312 Shi Q; Zhu LC; Cai CL; Yin JH; Costa G 收藏  |  浏览/下载：21/0  |  提交时间：2010/08/17 FREE-RADICAL POLYMERIZATION  LOW-DENSITY POLYETHYLENE  LASER-INDUCED EXPERIMENTS  TWIN-SCREW EXTRUDER  MALEIC-ANHYDRIDE  GLYCIDYL METHACRYLATE  CONVERSION DEPENDENCE  RATE COEFFICIENTS  MECHANISM  STYRENE
