Abstract

Nd3+ ions in KYF4 can occupy different sites. The energy transfer processes that take place between them are responsible for the unusual behavior of Nd3+. From the spectroscopic measurements at different temperatures we found an anomalous spectroscopic behavior in the low temperature range (20K - 100K). Based on an energy transfer model, we proposed an explanation to this abnormal behavior. We derived the formula to describe the deexcitation process and make a data fitting on our dynamic decay measurements.
