“…Hence, wet chemical synthesis methods are highly applicable for their synthesis (Gai et al 2014). The literature on phosphors prepared by modified Pechini methods is extensive, including host materials such as CaIn2O4 ), Ca8La2(PO4)6O2 (Shang et al 2012), YVO4 (Serra et al 2000), YNbO4 (Lü et al 2015) and SrZrO3 (Zhang et al 2008). In some of these reports the materials are also prepared by solid-state reactions for comparison, and the modified Pechini-powders are shown to have equal or better properties (Wang et al 2008b).…”

The modified Pechini method has become one of the most popular synthesis methods for complex oxide materials due to its simplicity and versatility. The method can be applied to synthesize nano-crystalline powders, bulk materials as well as oxide thin films. Here, we present a comprehensive review of the method with focus on the chemistry through the three stages of the process; preparation of stable aqueous solution, poly-esterification to form a solid polymeric resin and finally decomposition/combustion of the resin to form an amorphous oxide followed by crystallization of the desired oxide phase. The review include

“…Eu 3+ -doped BaZrO 3 phosphors also show the merits of brightness and flexible industrial processing ability, and they are suitable for lighting and display devices. As such, more and more investigations are focused on luminescent properties and mechanisms of rare earth ion-doped BaZrO 3 [8], in which Yb 3+ [9], Tm 3+ [9], Eu 3+ [10,11], Ti +4 [11], and Tb 3+ [12] have been developed as dopants in BaZrO 3 powder, and their luminescent properties and corresponding mechanisms were discussed.…”

Abstract:In this study, BaZrO 3 :Eu 0.025 powder was synthesized through the solid-state reaction method with two different heating processes. For the one-step process, the BaZrO 3 :Eu 0.025 powder was heated to 1000˝C-1400˝C for 2 h. For the two-step heating process, the BaZrO 3 :Eu 0.025 powder was pre-heated at 800˝C for 2 h, after being cooled to room temperature and ground, then the powder was heated to 1000˝C-1400˝C again for 2 h. The optimum excitation optical wavelength of BaZrO 3 :Eu 0.025 powders were 271 nm and the maximum intensity of the emission spectrum of BaZrO 3 :Eu 0.025 powders increased with increasing heating temperature. The all-heated BaZrO 3 :Eu 0.025 powders showed two strong orange emission bands peaking at the wavelengths of 574 and 596 nm and two weak emission bands peaking at 620 and 650 nm. As the heating temperatures were 1300˝C and 1400˝C, the maximum intensity of one-step heating BaZrO 3 :Eu 0.025 powders appeared at the 5 D 0 -7 F 0 (574 nm) and the maximum intensity of one-step heating BaZrO 3 :Eu 0.025 powders appeared at the 5 D 0 -7 F 1 (596 nm) transitions of Eu 3+ ions, respectively.

“…Previously, the solid-state reaction method was explored to synthesize BaZrO 3 :Eu 3+ phosphors. (5,9,10) The luminescence properties and the effects of dopant concentration on the PL characteristics of BaZrO 3 :Eu 3+ phosphors were investigated on the basis of excitation and emission spectra. Kanie et al synthesized Eu-doped BaZrO 3 fine particles with high crystallinity by the hydrothermal reaction method and they obtained spherical, rhombic dodecahedral, and flower-shaped BaZrO 3 fine particles.…”

In this study, the raw materials of BaCO 3 and ZrO 2 powders with different average diameters were used to prepare BaZrO 3 :Eu 0.025 phosphors by the solid-state reaction method. The raw materials with different average diameters were prepared by mixing them by the ball milling method and/or grinding them in a nanoscale grinding machine. As different grinding processes were used, the BaCO 3 and ZrO 2 powders had the average diameters of 2124, 707, 645, and 496 nm. When raw materials with the average diameter of 2124 nm were used and the calcination temperature was changed from 1100 to 1400 °C, the BaZrO 3 :Eu 0.025 phosphors showed two strong orange emission bands with peaks at the wavelengths of 574 and 596 nm and two weak emission bands with peaks at 620 and 650 nm. The maximum intensity of the emission spectrum of the BaZrO 3 :Eu 0.025 phosphors increased with increasing calcination temperature. When the raw materials with the average particle sizes of 707, 645, and 496 nm were used and the calcination temperature was changed from 950 to 1150 °C, the BaZrO 3 :Eu 0.025 phosphors showed one broad blue emission band with central wavelengths located at 464-466 nm. In this study, we prove that when the sizes of the source materials are different, the luminescence properties of the BaZrO 3 :Eu 0.025 phosphors will have large variations after they are calcined at different temperatures.
