%X The thermal and the ultraviolet radiation degradation mechanisms of lamp used BaMgAl10O17:Eu2+, Mn2+ phosphor are investigated in a comparative way. Thermal and the ultraviolet radiation treatments can both seriously damage the luminous efficiency of BaMgAl10O17:Eu2+,Mn2+. It is revealed that the thermal degradation is involved in the oxidation and migration of Eu2+ ions. The ultraviolet radiation makes the Eu2+ in metastable state, which weakens the direct absorption of Eu2+ and thus reduces the relative luminescence intensity of BaMgAl10O17:Eu2+,Mn2+.
