“…SCS of phosphate-based phosphors include preparation of water-based reactive slurries of metal nitrates, ammonium dihydrogen phosphate, and urea followed by ignition in preheated furnaces at temperatures between 500– 600 °C. − For incorporation of fluorine into the crystal structure of phosphors, ammonium fluoride was also added into reactive solutions and slurries. , In most cases, postsynthesis annealing in air at temperatures between 800–1200 °C was applied. It is reported that for the preparation of Eu 2+ activated phosphors, the annealing stage should be performed in reductive atmosphere. − For example, Tang and Xue reported SCS of a series of orthophosphate solid solutions with a general formula of Sr 8 Mg 1– m Zn m Y(PO 4 ) 7 :Eu 2+ by immersion of reactive solutions in preheated furnace for 5 min to initiate the combustion reaction .…”

Solution combustion is an exciting phenomenon, which involves propagation of self-sustained exothermic reactions along an aqueous or sol-gel media. This process allows for the synthesis of a variety of nanoscale materials, including oxides, metals, alloys, and sulfides. This Review focuses on the analysis of new approaches and results in the field of solution combustion synthesis (SCS) obtained during recent years. Thermodynamics and kinetics of reactive solutions used in different chemical routes are considered, and the role of process parameters is discussed, emphasizing the chemical mechanisms that are responsible for rapid self-sustained combustion reactions. The basic principles for controlling the composition, structure, and nanostructure of SCS products, and routes to regulate the size and morphology of the nanoscale materials are also reviewed. Recently developed systems that lead to the formation of novel materials and unique structures (e.g., thin films and two-dimensional crystals) with unusual properties are outlined. To demonstrate the versatility of the approach, several application categories of SCS produced materials, such as for energy conversion and storage, optical devices, catalysts, and various important nanoceramics (e.g., bio-, electro-, magnetic), are discussed.

The evaluation of trapping parameters activation energy, frequency factor, electron's life time in traps, capture cross-section, kinetics order, etc. are the most important studies in the field of themoluminescence. The thermoluminescence (TL) properties of Pr and (Ag, Pr) doped ZnSe phosphors are studied at three uniform heating rates between the temperature of 130K and 370K after excitation by UV radiation (365 nm). Trapping parameters of these phosphors have been determined and its nature is discussed.

“…The main reason of emphasizing on borate is their variety of structure types, transparency to a wide range of wavelengths, high laser damage tolerance, and high optical quality (Bajaj and Omanwar 2013). Combustion synthesis is a good low-cost, one-step, and lowtemperature method for the synthesis of borates, phosphates, and silicates (Khan et al 2015;Bhatkar et al 2002;Thakare et al 2007;Bhatkar et al 2007;Sonekar et al 2007;Sonekar et al 2009). Some orthoborates, LiMgBO 3 :Dy 3+ (Bajaj and Omanwar 2014), NaCaBO3 (Wu et al 2005) (Kumar et al 2013), NaCaBO 3 : Ce 3+ , Mn 2+ (Sun et al 2013), NaCaBO 3 :Ce 3+ , Tb 3+ , Mn 2+ (Zhang and Gong 2014), NaCaBO 3 :Sm 3+ (Bedyal et al 2014), etc., have been synthesized with different methods to explore their crystal structure and luminescent properties for probable applications in medical as well as industrial fields.…”

Rare earth (Dy(3+) and Sm(3+))-doped sodium magnesium borate (NaMgBO3) is synthesized by solution combustion synthesis method keeping their thermoluminescence properties in mind. The reaction produced very stable crystalline NaMgBO3:RE (RE = Dy(3+), Sm(3+)) phosphors. The phosphors are exposed to (60)Co gamma-ray radiations dose of varying rate from 5 to 25 Gy, and their TL characteristics with kinetic parameters are studied. NaMgBO3:Dy(3+) phosphor shows two peaks for lower doping concentration of Dy(3+) while it reduced to single peak for the higher concentrations of activator Dy(3+). NaMgBO3:Dy(3+) shows the major glow peak around 200 °C while NaMgBO3:Sm(3+) phosphors show two well-separated glow peaks at 200 and 332 °C respectively. The thermoluminescence intensity of these phosphors was compare with the commercially available TLD-100 (Harshaw) phosphor. The TL responses for gamma-ray radiations dose were found to be linear from 5 to 25 Gy for both phosphors while the fading in each case is calculated for the tenure of 45 days.
