Preparation and its luminescent properties of AlPO4:Eu3+ phosphor for w-LED applications

The thermal stability and structural site-distribution of Eu3+ ions in the red-emitting phosphors Ca9Eu2W4O24 and Sr9Eu2W4O24

“…There have been extensive studies on new phosphors for W-LEDs [3][4][5][6][7][8][9][10]. In particular Eu 3+ -doped oxyacid materials such as tungstates [11], silicates [14], vanadates [15], borates [16] and phosphates [11][12][13][14][15][16][17] have been investigated for red emitting phosphors.…”

Preparation and luminescence characterization of new carbonate (Y2(CO3)3·nH2O:Eu3+) phosphors via the hydrothermal route

“…The emission spectra were measured with an excitation wavelength of 254 nm. All obtained samples displayed 5 D 0 → 7 F J (J = 1, 2) lines of Eu 3+ ions [15]. The strongest emission was at 615 nm, corresponding to the 5 D 0 → 7 F 2 transition.…”

“…The intensities of the excitation peaks increased with increasing heating temperatures. These excitation peaks at 320, 364, 384, 396, 419, and 466 nm corresponded to the spectral transition of 7 F 0 → 5 H 6 , 7 F 0 → 5 D 4 , 7 F 0 → 5 G 2 , 7 F 0 → 5 L 6 , 7 F 0 → 5 D 3 , and 7 F 0 → 5 D 2 , respectively [15]. The dominant one was 7 F 0 → 5 L 6 transition (396 nm).…”

A Facile Synthesis and Optical Properties of Bundle-Shaped TbPO4·H2O Nanorods

“…The chemical and optical properties of one-dimensional (1D) LnPO 4 nanostructures (e.g., CePO 4 : Tb 3+ nanowires, LaPO 4 nanorods, CePO 4 peanut-liked nanostructures, etc.) can be successfully tailored, which makes these materials have significant potential applications in fabricating the next generation of information storage, optoelectronic, sensing devices, and nanoscale devices [13][14][15].…”
