Spectroscopy of BeAl(2)O(4):Cr(3+) with application to high-temperature sensing.
Characterization of absorption, emission, and temperature-dependent luminescent features is of significant interest for the development of optical temperature sensors and photonic devices. In this work, we conduct a comprehensive study to evaluate the orientation axis-dependent absorption and emission cross sections of Cr(3+) ions in BeAl(2)O(4). In addition, we present new data for the temperature-dependent Stark-level energies for alexandrite. Laser-induced temperature-dependent luminescence data from 300-520K on the R-line transitions are presented for application to high-temperature sensing.
