Abstract
Инфракрасный люминофор на основе оксисульфида иттрия, активированный трехвалентными ионами эрбия, отличающийся тем, что, с целью уменьшения видимой антистоксовой люминесценции и повышения стоксовой ИК-люминесценции в области 1.5-1.6 мкм при возбуждении лазерным излучением диапазона 0.90-0.98 мкм, он дополнительно содержит в катионной подрешетке оксисульфида иттрия трехвалентные ионы церия и имеет химический состав, соответствующий следующей эмпирической формуле: ! Y2-x-уErxCeуO2S, ! где х=0.20-0.45; 1·10-7≤у≤5·10-3.Yttrium oxysulfide infrared phosphor activated by trivalent erbium ions, characterized in that, in order to reduce visible anti-Stokes luminescence and increase Stokes IR luminescence in the region of 1.5-1.6 μm when excited by laser radiation in the range 0.90-0.98 μm, it additionally contains in cationic sublattice of yttrium oxysulfide is trivalent cerium ions and has a chemical composition corresponding to the following empirical formula:! Y2-x-уErxCeуO2S,! where x = 0.20-0.45; 1 · 10-7≤y≤5 · 10-3.
