Abstract
Absorption, emission spectra under UV and X-ray excitations, as well as luminescence decay kinetics of GGG:Bi single crystalline films were studied. The emission spectra observed in the spectral region 350–700 nm at room temperature consist two elementary bands peaked at 446 and 521 nm. The influence of growth conditions on the optical-luminescent properties of GGG: Bi <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> garnet have been revealed. The ratio of the bands intensities in luminescence spectra under different types of excitation and their temperature dependencies were determined.
