“…However, the sulfide phosphors are not stable and not bright enough for many applications. Therefore, industrial production of long-afterglow phosphors has been switched to rare-earth-ions doped alkali earth aluminates and oxysulfide based phosphors, such as SrAl 2 O 4 :Eu, Dy (green) [4], CaAl 2 O 4 :Eu, Nd (blue) [5], rare-earth-ions doped oxysulfide yttrium (red or reddish-orange) [6][7][8] and Dy 3+ , Mn 2+ -codoped Mg 2 SiO 4 (red) [9]. The brightness of these phosphors is greatly improved compared with that of the previous sulfide phosphors and without doping any radioactive materials.…”

“…The preparations of phosphors mainly focus on the high-temperature solid-state reactions providing agglomerated powders, which can change the structural characteristics of the powders [30,14,15,[36][37][38]. Recently, the development of new methods for the synthesis of micro or nano phosphors may increase the probability for high effective rare-earth phosphors [39][40][41][42][43][44][45][46][47][48]. Solution combustion synthesis (SCS) has emerged as an attractive technique for the synthesis of high purity homogeneous and crystalline oxide powders at signifi cantly lower temperatures than the conventional synthesis method, because the starting materials which are used are homogeneously mixed in liquid phase and the impurities with low boiling points can easily get evaporated at high temperature generated instantly during exothermic reaction [49][50][51][52].…”

“…These feature transitions within the 4f n configuration have found an important application in the luminescent probes or labels for chemical or biological macromolecules [3], the active center for luminescent materials [4] and electroluminescent devices [5]. During the past decade, a significant success has been achieved in the synthesis of nanosized rare earth phosphors by a variety of methods, such as spray pyrolysis [6], colloidal reactions [7], combustion synthesis [8], so-called wet or soft chemical technology [9][10][11][12] and so on. But in most cases, the syntheses primarily focused on the high-temperature solidstate reactions providing agglomerated powders, which can allow to readily alter the structural characteristics of the solid powders [13,14].…”
