Synthesis, energy transfer and luminescence properties of KSrVO4:Eu3+ red phosphor

Synthesis, energy transfer, charge compensation and luminescence properties of CaZrO3:Eu3+, Bi3+, Li+ phosphor

“…The PL spectral shapes and peak positions are the same except PL intensity. PL spectrum of CaZrO 3 :5% Eu 3+ phosphor within the range 550-725 nm contains four PL band peaks, which are attributed to the 5 D 0 → 7 F 1 (~ 590 nm), 5 D 0 → 7 F 2 (~ 614 nm), 5 D 0 → 7 F 3 (~ 655 nm), and 5 D 0 → 7 F 4 (~ 705 nm) transitions of Eu 3+ ion, respectively [27]. PLE spectrum of CaZrO 3 :5% Eu 3+ phosphor monitored at 614 nm includes a broad PLE band and many narrow PLE bands in the range of 220-550 nm.…”

Mn2+ doped SrSn(PO4)2 nanopowder for new novel LED material

“…Nanomaterials far more fascinating compared to bulk materials because of quantum confinement effects, a high surface-to-volume ratio, optical, electronic and magnetic properties shared to extremely fine-grained counterparts [13]. Fourth generation white light emitting diodes have been developed into lighting fixtures that are more energy efficient, brighter, quicker to respond, stable, and have been more popular than previous generations of lighting devices [14][15][16][17]. An enhanced WLED has been designed by using single-component white phosphor and Ultra Violet LED chips which have advantages of efficient illumination and simpler manufacture [18].…”
