Synthesis and characterization of BaMgAl10O17:Eu2+ phosphor prepared by homogeneous precipitation

Photoluminescence and EPR studies of BaMgAl10O17:Eu2+ phosphor with blue-emission synthesized by the solution combustion method

“…are fully crystalline with hexagonal phase at furnace temperature of 500 o C and therefore a post-calcination treatment for crystallization is not required. It has been reported in the literature that pure hexagonal phase of BaMgAl 10 O 17 is usually obtained at higher temperature ( o1200 1C) and there is always a possibility of the formulation of the intermediate BaAl 2 O 4 at lower reaction temperatures [13,14]. Even though the starting materials were mixed according to the chemical composition of BaMgAl 10 O 17 :Eu, other possible intermediate phase BaAl 2 O 4 might be formed at low temperature combustion process.…”

Spectroscopic study and enhanced thermostability of combustion-derived BaMgAl 10 O 17 :Eu 2+ blue phosphors for solid-state lighting

“…This is particularly interesting since the current trend in the field of lighting devices is to develop large luminescent areas. Furthermore, it has been notably reported [39,40] that the phosphors prepared via wet chemical processes exhibited stronger emission intensity and higher thermal stability than the samples derived from solidstate reaction.…”

Microwave-Induced Combustion Synthesis of Luminescent Aluminate Powders

“…These synthesis routes lead to microsized particles exhibiting surface defects and a large particle size distribution, which is prejudicial to optical performances. The necessity to develop nanostructured phosphors has entailed the emergence of numerous chemical synthesis techniques for these aluminates: solvothermal, sol-gel, co-precipitation, spray pyrolysis... (Kang et al 1998;Lee et al 2009;Lu et al 2006;Pan et al 2004;Potdevin et al 2007;Zhang et al 2010). These methods involve a homogeneous mixing of metal ions by using precursors in solution.…”
