Piezoelectric detection of photoacoustic signals offers a number of advantages over the better known microphonic technique for condensed phase samples. Experimental techniques are greatly simplified by taking advantage of the acoustic impedance match offered by solid state detectors with solid or liquid samples. Such piezoelectric detectors prove suitable for ac steady state measurements as well as impulse-transient response detectors. Several example spectra of Nd(III) are presented with emphasis on the effects of the fluorescence-lifetime in Nd:glass laser material.
与更为人熟知的用于凝聚相样品的微音器技术相比，压电检测光声信号具有诸多优势。利用固态探测器与固体或液体样品之间的声阻抗匹配，实验技术得以大大简化。此类压电探测器适用于交流稳态测量以及脉冲瞬态响应检测。给出了钕（III）的几个示例光谱，重点关注了钕玻璃激光材料中荧光寿命的影响。
