“…Silicate phosphors are interesting due to their high stability as compared to aluminates or sulfides. The preparation of different phosphors by SCS, such as yttrium, , cadmium, , or alkaline-earth − metal silicates, is more difficult than other complex multielement compounds. Typically, the reactive solution that is utilized to prepare these nanophosphors involves metal nitrates, fuels, and high surface area silica.…”

“…Shinde et al prepared Cd 2 Si 2 O 7 :Ce nanophosphors with a triclinic crystal structure utilizing reactive gels of metal nitrates, glycine, and silica. 587 It was shown that gels ignited at 580 °C yield amorphous materials, which could be crystallized during the calcination stage at 1000 °C for 2 h. However, pure phase product could only be obtained at 1200 °C. The authors also outline that the solid-state synthesis of Cd 2 Si 2 O 7 :Ce phosphors can be only achieved during 20 h heating of the simple oxide mixture at 1400 °C.…”

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.

“…7(a), curve 4) the PL spectrum exhibits a broad emission in the 380-600 nm spectral range with its maxima at 400 nm and 420 nm specific for accommodation of Ce 3 þ in Ce1 sites in Y 2 SiO 5 host lattice. The broad nature of emission is the consequence of two electron transition in Ce 3 þ from 5 d level to the ground state levels ( 2 F 5/2 , 2 F 7/2 ) separated by 0.25 eV [48]. The emission intensity decreases significantly as the excitation wavelength decreases from 353 nm to 265 nm.…”
