Abstract

β-Ga₂O₃, an advanced semiconductor optical material, exhibits remarkable luminescence properties through doping. In this study, β-Ga₂O₃:Bi single crystals were successfully grown using the optical floating zone method, and their luminescence mechanisms were investigated. Our results demonstrate that reducing the sintering temperature to 1000 °C enhances the incorporation of Bi into the crystal matrix. Temperature-dependent spectral analysis reveals the non-radiative transitions in the blue light region, contributing to fast luminescence dynamics. These findings deepen our understanding of the luminescence characteristics of β-Ga₂O₃ single crystals and provide valuable insights for potential applications in radiation detection.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
