Combustion synthesis and photoluminescence of SrAl2O4:Eu,Dy phosphor nanoparticles

Laser synthesis and luminescence properties of SrAl2O4:Eu2+, Dy3+ phosphors

“…They are used in safety and emergency signs, as well as in luminous markings in watches and other instruments' dials. sol-gel-microwave processes, 13 as well as hydrothermal and combustion methods 14,15 have been successfully developed to produce strontium aluminate phosphors at lower synthesis temperatures and within shorter reaction times.…”

Synthesis and luminescent properties of nanocrystalline CaYAlO4:Sm3+ phosphors

“…To achieve high-performance devices, thus, it is necessary to develop novel phosphors with good chemical durability, high luminescence efficiency, and pure chromatic emission. There have been many wet chemistry methods to synthesize phosphor materials including sol-gel [6,7], hydrothermal synthesis [8], spray-pyrolysis [9], and co-precipitation synthesis techniques [10]. Among these methods, the solgel method has many advantages such as simple process, good control of stoichiometry, homogenous composition, and low processing temperature [11][12][13] 3 Á 6H 2 O) with different concentrations was used as an activator.…”

The influence of different species of gases on the luminescent and structural properties of pulsed laser-ablated Y2O2S:Eu3+ thin films

“…Moreover, it is well documented that thin-film phosphors have several advantages over powders, such as higher lateral resolution from smaller grains, better thermal stability, reduced out gassing and better adhesion to solid substrates [18]. Among the techniques used to prepare luminescent thin films, PLD has several attractive features, including stoichiometric transfer of the target material, generation of quality plume of energetic species, hyper-thermal reaction between the ablated cations and molecular gas in the ablation plasma and compatibility with background pressures ranging from UHV to 100 Pa [19]. The plasma fabricated during pulsed laser ablation is very energetic, and its mobility can be easily controlled by changing processing parameters [20].…”
