title: Laser photoacoustic spectra of Sm3+ ion in Sm2O3 and SmCl3.6H2O in the spectral profile 484-542 nm.
abstract: Microphone based photoacoustic (PA) spectrometer to study solids in powder form was designed and fabricated. Laser PA spectra of Sm3+ ion in Sm2O3 and SmCl3.6H2O microcrystalline powders were recorded first time in 484-542 nm spectral region at room temperature. Analysis of these PA spectra shows new information on the Stark components of ground and excited states of Sm3+ ion. A comparison of Stark energy levels of Sm3+ ion in both oxide and hexahydrated chloride hosts is presented here.
