FIELD: chemistry.SUBSTANCE: invention relates to chemical industry and can be applied in production of luminescent marks and registration of fast-proceeding processes. Fast-kinetising infrared luminophor based on yttrium or lanthanum oxisulfate possesses hexagonal structure and has chemical composition, described by the following empirical formula: (LnNdPr)OS, where Ln=Y, La; 2,5·10?x?2·10; 1·10?y?5·10.EFFECT: when excited by laser radiation of the range 0,8-0,82 mcm, luminophor has increased intensity of two groups of IR-bands of luminescence in spectrum regions 1,03-1,12 mcm and 1,30-1,45 mcm.2 dwg, 1 tbl, 14 ex |
