Abstract
A study of the energy, spectral, temporal characteristics of corundum (a-Al2O3) with various activators was made to develop a more efficient converter of UV radiation not only in the UV, but also in the VUV spectral regions. Promising activating agents were selected, their concentrations were determined, their optical properties were studied, absorption and luminescence spectra (curves) were obtained, and quantum yields were measured at various impurity concentrations. Luminescence measurements were carried out at several constant corundum irradiation frequencies (dependence of luminescence on radiation power) within the limits of the capabilities of the available equipment. Luminescence is the most important characteristic of crystals in the development of optical detectors based on them.
