POSSIBLE WAYS OF RELAXATIONS FOR EXCITED STATES OF RARE EARTH IONS IN AMORPHOUS MEDIA
R. Reisfeld et M. EyalDepartment of Inorganic and Analytical Chemistry, The Hebrew University of Jerusalem, 91904 Jerusalem, Israel
Abstract
The various mechanisms of relaxation of rare earths in glasses are outlined. Examples are given for radiative transfer as a means of increasing pumping efficiencies. Nonradiative relaxation of rare earths in oxide and fluoride glasses follow an exponential law when two glass former phonons are subtracted. Cross-relaxations are calculated for Pr(III), Ho(III) and Nd(III).
