摘要
用曙红敏化重铬酸盐明胶全息记录材料。用光声光谱技术测定了这种材料的光能吸收光谱。实验的结果表明，曙红是一种新的有价值的重铬酸盐明胶光谱增感染料，可以在５１４．５ｎｍ处形成强吸收峰，这对于记录彩色全息图和制作全息光学元件是有利的；光声光谱技术在全息记录材料的光谱增感与光化学过程的测量中，是一种极其灵敏又十分有效的方法。
The eosin is used to sensitize dichromated gelatin holographic recording material and photoacoustic spectroscopy (PAS)is adopted to measure its absorption spectrum.The experimental results prove that the eosin is a new and valauable spectral sensitized dye for dichromated gelatin.With the sensitization by the eosin,the dichromated gelatin's absorption becomes higher at 514.5 nm.Thus,this material can be advantageously used for recording full-color holograms and making holographic optical elements.At the same time,these results also show that PAS is an extremely effective way for the measurement of spectral sensitization and photochemical processes of holographic recording material.
