## Description

- description: Cr3+-doped Ga2O3 crystals with a corundum structure were synthesized
    under high temperature and high pressure, and their excitation as well as fluorescence
    properties were evaluated. The crystals were green under white light illumination
    but deep red when exposed to ultraviolet light. This is mainly attributable to
    R1 and R2 fluorescence spectra caused by the Cr3+ transition. The pressure-dependence
    of their fluorescence spectra is comparable with ruby (Al2O3:Cr3+), which is currently
    often used as a pressure scale. The excitation spectrum was shifted to the long-wavelength
    side compared with ruby, which enables excitation with long-wavelength lasers,
    even if the pressure effect is considered. In addition, the R1 and R2 peaks were
    well-separated with increasing pressure, which might have advantages over the
    ruby scale.
