VARIABLE-TEMPERATURE OPTOACOUSTIC STUDIES OF 4F-STATES OF NEODYMIUM IN OXIDE PHASES

[摘要] High resolution optoacoustic studies on a wealky absorbing 4f electron manifold of Nd3+ in several samples of Nd2O3 of varying purity are reported using a tunable, pulsed laser as the excitation light source. In cases where nonlinear optoacoustic was observed, good agreement was found between the observed response and a simple nonlinear optical absorption model. To resolve differing spectral assignments for bands of Nd3+ in Nd2O3 observed by conventional and optoacoustic spectroscopy, this work was carried out at sample temperatures ranging from 4 K to 295 K in an apparatus designed for studies on air- or moisture-sensitive materials.
