苯并咪唑的三维荧光光谱与三维室温磷光光谱

THREE-DIMENSION FLUORESCENCE SPECTRUM AND THREE-DIMENSION ROOM TEMPERATURE PHOSPHORESCENCE SPECTRUM OF BENZIMIDAZOLE

测量了浓度为 1× 1 0 - 4 mol/L苯并咪唑水溶液的三维荧光光谱 ,三维室温磷光光谱和紫外 /可见吸收光谱 ,还测量了苯并咪唑固体紫外 /可见吸收光谱 对化合物的荧光和室温磷光进行了分析、比较 ,发现苯并咪唑在 2 90nm、5 80nm和 870nm区域均有强而丰富的荧光谱线 ,而室温磷光谱线 (RTP)单一地出现在 2 90nm区域 ,且强度很小 ;

The Three dimension fluorescence, three dimension room temperature phosphorescence (RTP) and UV/VIS spectra of benzimidazole at the concentration of 1×10 -4 mol/L were measured, and also its solid′s UV/VIS spectrum. The fluorescence and RTP of the heading compound were analysised and compared, writer have found that benzimidazole had plentiful and powerful fluorescence spectra at the zone of 290 nm?580 nm and 870 nm. But the room temperature phosphorescence appeared at the zone of 290nm singly and weakly, as well as the up conversion fluorescence phenomenon was discussed.
