Paper Abstract

An anomalously high efficiency of sound photogeneration in the ensemble of spatially separated CdS microcrystals embedded in zeolite cavities and excited by nsec laser pulses is found. A qualitative explanation of the observed effect is made. The photoacoustic spectra of such specimens which were obtained by gas-microphone detection call made it possible to reconstruct the fundamental absorption edge of CdS microcrystals in the (alpha) less than 103cm-1 region. The presented results reflect the efficiency of the absorbed- to-thermal energy conversion.
