Luminescent properties of CaMgSi2O6-based phosphors co-doped with different rare earth ions

“…Yet, up to now, the use of CaMgSi 2 O 6 as the luminescent host is rarely reported. Pogrebisskaya et al [4] prepared CaMgSi 2 O 6 :Ti 4+ crystal phosphors by sol-gel synthesis and reported that the calcination process has a positive effect on the crystallization and the luminescence properties of the phosphors. Recently, Kunimoto [5] prepared blue-light-emitting CaMgSi 2 O 6 :Eu phosphors with a long lifetime using SiO 2 -rich source materials, and it is expected that CaMgSi 2 O 6 :Eu phosphor can be applied to plasma display panel (PDP) due to its resistance to luminance degradation by baking process.…”

Photoluminescence of Eu2+-doped CaMgSi2xO6+2x (1.00⩽x⩽1.20) phosphors in UV–VUV region

“…CaMgSi 2 O 6 doped with rare-earth and transition-metal ion phosphors have been studied by some researchers [8][9][10][11][12]. Among these studies, Kunimoto et al have prepared blue-emitting phosphor CaMgSi 2 O 6 :Eu 2+ with Si-rich mixture and it was concluded that the PL intensity under vacuum ultraviolet (VUV) excitation was enhanced with excess SiO 2 [11].…”
