ULTRAVIOLET-RADIATION PHOSPHOR COMPOSITION AND ARTIFICIAL TANNING LAMP INCORPORATING IT Russian patent published in 2007 - IPC H01J61/44 

FIELD: electrical engineering.

SUBSTANCE: proposed ultraviolet-radiation phosphor composition has mixture of at least two UVA radiating phosphors chosen from SrB₄O₇:EU, YPO₄:Ce and BaSi₂O_s:Pb in which mixture of UVA radiating phosphors has 0 to 50 mass percent of SrB₄O₇:EU, 0 to 40 mass percent of YPO₄:Ce, and 30 to 70 mass percent of BaSi₂O_s:Pb, total phosphor percentage being 100%. Phosphor composition can have in addition UVB radiating phosphor in the amount of 0 to 12 mass percent.

EFFECT: enhanced initial yield of mentioned ultraviolet radiation and its safety.
