Fabrication and characterization of calcium silicate phosphors -Ca2SiO4 and Ca2MgSi2O7-発表情報：Materials Sciecne Forrum 巻: 761 ページ: 59-64キーワード：概要：Calcium silicate phosphors, Ca2-xSiO4(CS):Eu3+ x, CS:Eu2+ x and Ca2-y-zMgSi2O7 (CMS):Eu2+ y,Dy3+ z were prepared by the solid state reaction. The phases in CS:Eu3+ system were ?- and ?L' -types. The fluorescent color under a black-light irradiation was red and the emission spectrum consisted of 590nm, 615nm and 625nm peaks. The emission intensity took a maximum value at x=0.2. The addition of B3+ accelerated the solid solution of Eu3+. The phase in CS:Eu2+ system was ?-type only. The fluorescent color was yellow-green(520nm). The emission intensity took a maximum value at x=0.01. The CMS product showed the akermanite phase. The lattice constants of CMS:Eu2+ increased with increasing Eu content, but those became constant at y>0.05. The fluorescent color of CMS:Eu2+ was yellow-green and the emission intensity took a maximum value at y=0.03. In the case of CMS:Eu2+ 0.03,Dy3+ z, the fluorescent color and the afterglow color were same, yellow-green. The emission intensity took a maximum value at z=0.06. The longest afterglow time, 23min., was obtained at z=0.09. The trap depth were 0.64-0.69 eV. � (2013) Trans Tech Publications, Switzerland.抄録：Calcium silicate phosphors, Ca2-xSiO4(CS):Eu3+ x, CS:Eu2+ x and Ca2-y-zMgSi2O7 (CMS):Eu2+ y,Dy3+ z were prepared by the solid state reaction.
