Title: Identification of multisite behavior in a broadly emitting transition-metal system using pressure

Abstract

We present a method based on the application of high pressure for identifying and distinguishing multiple bonding environments of a broadly emitting transition-metal dopant incorporated as an active luminescent center in a solid. The method involves using pressure to induce a broadband to sharpline spectral transformation via an electronic crossover. The spectral narrowing that occurs upon crossover permits resolution of spectroscopic features associated with different dopant bonding environments and allows us to determine the number of distinct bonding sites at ambient pressure. We specifically consider Cr{sup 3+}:LiTaO{sub 3} and show that its luminescence properties at ambient pressure are determined primarily by one low-field bonding environment with secondary contributions from a second low-field site.
