Cr3+doped Ca3(VO4)2: A new tunable laser crystal

Investigation on structure and photoluminescence properties of Ho3+ doped Ca3(VO4)2 phosphors for luminescent devices

“…They exhibit tunable emission characteristics; hence the color and intensity of emitted light can be tailored for specic applications. [11][12][13] This tunability is a crucial feature for creating phosphors that can complement the spectral sensitivity of human vision, resulting in optimal lighting and display quality. Ca 3 (VO 4 ) 2 , a type of vanadate, has a crystalline structure that, when doped with certain rare-earth ions, can be customized to emit light in the visible spectrum.…”

“…Kuz'micheva et al demonstrate the spectral-luminescent properties in Tm-doped Ca 3 (VO 4 ) 2 . 20 Voronina et al describe the yellow emission in Mn-doped Ca 3 (VO 4 ) 2 , 21 while Kuz'micheva et al show the presence of both Mn 2+ and Mn 3+ in manganese-doped Ca 3 (VO 4 ) 2 , 22 Chen et al describe the strong absorption at the visible wavelength in Cr-doped Ca 3 (VO 4 ) 2 , 13 and Ivleva et al report the optical homogeneity in Tm 3+ /Ho 3+ codoped Ca 3 (VO 4 ) 2 . 23 In recent years, the focus of research has extended to the doping of Ca 3 (VO 4 ) 2 with various rare-earth ions, including trivalent holmium (Ho 3+ ).…”
