Laser photoacoustic spectra of Sm3+ ion in Sm2O3 and SmCl3 center dot 6H(2)O in the spectral profile 484-542 nm

摘要

Microphone based photoacoustic (PA) spectrometer to Study solids in powder form was designed and fabricated. Laser PA spectra of Sm3+ ion in Sm2O3 and SmCl(3)(.)6H(2)O microcrystalline powders were recorded first time in 484-542nm 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. (C) 2003 Elsevier B.V. All rights reserved. [References: 10]
