Abstract
The steady state and transient fluorescence spectra of CaF2: Dy3+ have been studied using Ar+ and N2 lasers in the temperature range 77-673 K and in the wavelength region 4500-9000 Å The spectra show the presence of two types of centers (type A and type B) with decay times of 1.3 and 3.5 ms. The observed spectrum is mostly due to type A centers. Three new groups of fluorescence 4F9/2-(6H9/2,6F11/2) and4F9/2-(6H7/2,6F9/2) have been observed for type A centers, and a tentative assignment of the positions of the Stark levels of 6H11/2, (6H9/2,6F11/2 ) and (6H7/2,6F9/2 ) has been made. The change in the intensity of the transitions with temperature and excitation wavelength are discussed.
