“…Upon annealing at 1000 °C for 1 h, the full width at half‐maximum (FWHM) of the reflection peaks of both nanophosphors became sharper as a result of an improved crystallinity and an increased particle size. Xenotime‐type YVO 4 and YPO 4 have the tetragonal zircon structure (space group: I 4 1 /amd) and these isomorphic compounds could be readily intermixed into a homogeneous vanadate/phosphate solid solution 11–13, 21, 22. Compared to pure YVO 4 phase, the reflection peaks of our annealed nanophosphors shifted to a higher 2 θ .…”

“…However, uniform nanosizing of those phophors is often challenging due to the compositional complexity, lack of appropriate precursor, or sophisticated synthetic route. Instead, Y(V,P)O 4 and LaPO 4 phases that possess a high chemical and thermal stability can be chosen as host lattices for doping various rare earth ions in PDP application, since they show high excitation efficiencies under vacuum ultraviolet (VUV) irradiation 9–14. Moreover, doped Y(V,P)O 4 and LaPO 4 nanophosphors having a homogeneous size distribution and controlled particle shape can be readily prepared via wet synthetic routes such as hydrothermal,9–11, 15 co‐precipitation approaches,16, 17 and their derivatives.…”

“…Higuchi et al [11] have reported the preparation of LuVO 4 nanoparticles doped with Tm 3+ by means of a floating zone method under pure oxygen, resulting in elongated crystals that exhibited emission at 1.8 lm. Lai et al [18] and Zhang et al [10] have developed Tm 3+ -doped (Y,Gd)P 0.5 V 0.5 O 4 and Tm 3+ -doped YVO 4 nanoparticles by co-precipitation and polymerizable complex methods, respectively, but they have only reported emission bands in the visible region. Riman and co-workers [19] have reported the development of LaCl 3 particles doped with Tm 3+ at various concentrations and observed 1.47 lm emission, but no particle-size analysis was presented.…”

“…In addition sulphide based phosphors are known to generate harmful gases such as H 2 S and SO 2 under electron beam irradiation [37,38]. Moreover, Tm 3 + doped YVO 4 or GdVO 4 could be ideal candidate for blue emitting phosphor in plasma display panel (PDP) since commercial PDP blue emitter BaMgAl 10 O 17 :Eu 2 + has easy aging problem due to lattice deformation of the host and oxidation of divalent europium ions [39].…”
