A SEARCH FOR HOST SENSITIZED LUMINESCENCE OF RARE EARTH IONS IN Sr2ZrP2O9
Abstract
The compound Sr2ZrP2O9 belongs to a family of host luminescent materials whose properties appeared to be favorable for the production of host- sensitized luminescence. However, measurements which were performed on this compound activated by rare earths indicated that little or no sensitization was taking place. An estimate of the expected sensitized luminescence yields in dicates that the failure to obtain sensitization can be accounted for by the low oscillator strengths of the rare earth ions. It suggests that rare earth ions are in general not well suited as activators in host sensitized systems except at comparatively high concentrations.
