The luminescence spectrum of divalent europium (Eu^<2+>) has characterized by intense and broad peak excited by UV light. Then Eu doped phosphates are one of the useful phosphor in the visible light range. We reported here luminescence properties of Eu-doped phosphate compounds SrMg_2(PO_4)_2. The samples prepared in H_2/Ar gas flow were the largest and the sharpest luminescence spectrum in 410 nm band identified the transition from divalent europium ions. The spectra showed broder and smaller shapes in the condition of condition of lower temperatures sintering or in ambient air. Elasticoluminescent has not obtained by all these samples in this time.}, pages = {77--79}, title = {焼結法によって作製したユーロピウムを添加したSrMg_2(PO_4)_2蛍光体の作製条件による発光特性の変化}, volume = {43}, year = {2014}, yomi = {マエダ, コウジ and フジハラ, コウジロウ and クメダ, トモアキ and サカイ, ケンタロウ and フジハラ, コウジロウ and クメダ, トモアキ} }
