Abstract
A piezoelectric detection system for recording photoacoustic (PA) spectra of materials in the condensed phase was designed and fabricated. A Nd–YAG laser pumped tunable dye laser with a bandwidth of 0.05 nm was used for recording the fine structure of bands in the region between 610–680 nm in powdered microcrystalline samples of Ho2O3 and Nd2O3. Analysis of high resolution photoacoustic spectra obtained new information on the Stark components of the ground and excited states of Ho3+ and Nd3+ in the oxide matrix.
