Luminescence properties of LiY6O5(BO3)3:Eu3+/Sm3+ phosphor

Sol-gel method for preparing a novel red-emitting phosphor YVO4:Sm3+, Eu3+ with ideal red color emission

“…White-light-emitting diodes (W-LEDs) has become a hotspot in energy-conservation research [1].The energy savings of W-LEDs is estimated to be 80% of incandescent lamps and 50% of fluorescent lamps. W-LEDs are also gaining popularity because of their reliability, long service life, compactness, and environment friendliness [2,3].…”

“…However, fluorescence quenching is observed in doping a certain proportion of lanthanide elements. The effect of doping concentration on luminescence properties and the energy-transfer mechanism between Sm 3+ and Eu 3+ have been investigated in these phosphors [1,10]. Many methods can M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 be used to prepare YVO 4 phosphors doped with Ln 3+ ions, including the methods of co-precipitation [11], hydrothermal [12,13], solvothermal treatment [14], microwave treatment [15], and sol-gel synthesis [16,17].…”
