Abstract:
An extensive investigation of the spectroscopic properties of NdxY1-xP5O14 is reported. Time-resolved site-selection spectroscopy and photoacoustic spectroscopy techniques were used as well as standard optical spectroscopy measurements which were made as a function of Nd concentration, temperature, excitation wavelength and laser power. Results show that Nd ions occupy a variety of slightly perturbed sites. No significant energy transfer appears to be taking place between ions in these inequivalent sites. Additional experimental data presented here suggests a new quenching model for neodymium pentaphosphate crystals based on spatial but non-spectral energy migration to surface quenching sites. Author
