Abstract:

We have developed a procedure for thermally stimulated synthesis of a cesium strontium metavanadate, Cs2Sr(VO3)(4):Mn2+ (0.01, 0.50, 1.00, 5.00 at \% Mn2+), using MnO-containing starting mixtures. The EPR spectrum of the material containing 0.01 at \% Mn2+ shows a hyperfine structure due to the incorporation of a small amount of manganese into the diamagnetic double metavanadate host. The luminescent and optical properties of Cs2Sr(VO3)(4):Mn2+ depend on manganese content. In contrast to higher doping levels, doping with 0.01 at \% Mn2+ increases the integrated emission intensity of the vanadate by 10\% and improves its chromaticity characteristics (approaching them to those of white light). We assume that this is due to the reduction in the density of vacancy-type growth defects, such as oxygen vacancies.
