摘要：图1是HR-101吸收光谱和荧光光谱,可以看到吸收谱与荧光谱主要部分是镜像对称的,而且有交迭,说明染料有自吸收,可以通过浓度和光程长度改变使得调谐范围朝长波移动。其它几种染料的吸收谱和荧光谱列于表1。 荧光量子效率用声光谱技术可作绝对测量。对新激光染料的测量结果列于表2。用氮分子激光作激发源,用宽带示波器和PIN管测得的染料荧光寿命也列于表2。
This paper reports that some novel infrared laser dyes with tuning wavelength from 670. 0 nm to 910. 0 nm was pumped by N2laser, and was made on laser properties, spectrum of fluorescence, fluorescence quantum efficiency and fluorescence lifetime was investigated. The fluorescence quantum efficiency was measured by opto-acoustic spectroscopy.
