In the present investigation dysprosium doped strontium aluminate phosphor was prepared by combustion synthesis method. The crystal structure of the prepared phosphor was consistent with standard monoclinic phase with a space group P2 1 . According to the TEM analysis, the particle size was found to be in the nanometer range. The trap parameters which are mainly activation energy (E), frequency factor (s) and order of the kinetics (b) were evaluated by using the peak shape method. Under the ultraviolet (365 nm) excitation, photoluminescence (PL) spectra showed characteristic emission bands at 480 (blue), 573 (yellow) and 670 nm (red) due to 4

“…These three different emission bands originated from one origin owing to the fact that they are having the same excitation wavelength. The transition involved in blue, yellow and red bands of Dy 3+ ion are well known and have been identified as 4 F 9/2 → 6 H 15/2, 4 F 9/2 → 6 H 13/2 and 4 F 9/2 → 6 H 11/2 transitions, respectively (Kuang and Liu 2006). Figure 8 shows the concentration vs 573 peak intensity graph of Sr 3 (VO 4 ) 2 :Dy phosphor.…”

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.
