FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electrical engineering, in particular to one-component UV-radiation phosphor that can be used in fluorescent lamps for skin sunburn and feature common composition (Y1-x-y-zLaxGdyCez )PO4, where x varies from 0.001 to 0.98, y varies from 0 to 0.1, z varies from 0.01 to 0.2, while x+y+z<1. When excited by 254 nm-radiation, phosphor radiates in UV A and B ranges. UV A-to-B ratio can be varied by adjusting relative quantities of Y and La. ^ EFFECT: one-component UV-radiation phosphor with wide UV A-to-B ratio range. ^ 17 cl, 3 dwg, 3 tbl, 3 ex |
