摘要:菁是一种具有多功能用途的染料,除用作卤化银感光材料及有机光导材料的光谱增感剂、光记录材料中记录介质外,还可作为染料激光器中用的激光染料.我们曾合成了四甲川苯乙烯菁、五甲川(艹粦)及五甲川吡喃鎓等红外染料作为激光染料,测定了它们的光性能.本文合成了具有桥链的七甲川菁,研究了这些桥链七甲川菁的吸收光谱及荧光光谱,并以YAG激光倍频(532nm)作泵浦源,测定了它们的激光调谐范围、中心波长及激光转换效率.
Five heptamethine cyanine dyes containing a diphenylamino group at the meso position in their bridge chain were synthesised. Their absorption spectra and fluorescence emission spectra were determined. The lasing properties of these dyes, including the tuning range, the center laser wavelength, and the conversion efficiency were examined with the pump source of the frequency-doubled YAG laser(532 nm).
