“…Recently, luminescence materials doped with Dy 3+ have drawn much interest for their white emission (DominiakDzik et al 2004;Xiu et al 2006;Liang et al 2008). In general, Dy 3+ has two dominant bands in the emission spectra in many host matrices.…”

Combustion synthesis and photoluminescence (PL) characterization of Sr 3 (VO 4 ) 2 :Eu,Dy phosphors are presented in this paper. PL emission of Sr 3 (VO 4 ) 2 :Eu phosphor shows green broad emission band centring at 511 nm and a red sharp band at 614 nm by excitation wavelength of 342 nm. The PL emission spectrum of Sr 3 (VO 4 ) 2 :Dy phosphor exhibits an intense blue emission peak at 479 nm, yellow broad band centring at 573 nm and red band at 644 nm by the excitation wavelength of 426 nm in near visible blue region. The excitation wavelength of Eu (342 nm) and Dy (426 nm) activated Sr 3 (VO 4 ) 2 phosphor are well matched with the excitation of near UV excited solid state lighting and blue chip excitation of light emitting diodes, respectively. The effect of Eu 2+ and Eu 3+ ions concentration on the emission intensity of Sr 3 (VO 4 ) 2 was also investigated. The Sr 3 (VO 4 ) 2 :Eu is a potential green and red emitting phosphor as well as Sr 3 (VO 4 ) 2 :Dy is blue and yellow emitting phosphor for solid state lighting i.e. white LEDs. The XRD and SEM characteristics of Sr 3 (VO 4 ) 2 materials was also reported in this paper.

“…White light-emitting glass was first developed by Zhang et al in 1991 [10], and it receives increasing interest in recent years [11][12][13][14]. However, only a few studies were concerned on glass ceramics [15,16].…”

“…Up to the present, visible emissions have been demonstrated from RE ions such as Ce 3+ , Tb 3+ , Er 3+ , Tm 3+ , Pr 3+ , Eu 3+ , Sm 3+ and so on [3][4][5][6][7]. Among all RE ions, the Ce 3+ ion has received much attention and there have been a lot of reports on the Ce 3+ ions doped luminescent materials in the last several years, for examples, Ce 3+ -doped YAG phosphor and glassceramic for white light emitting diode [6,8].…”
