“…XRD measurement confirmed the formation of crystalline phase in the as prepared sample. The recorded XRD pattern is in good agreement with the standard pattern for hexagonal BaMgAl10O17 with P63/mmc space group (JCPDS 00-26-0163) [2]. Traces of an intermediate phase BaAl2O4 (JCPDS 01-082-1350) were also observed.…”

“…BaMgAl10O17:Eu 2+ is considered as a desirable blue phosphor for its excellent chemical stability, high luminance efficiency and good chromaticity under both ultraviolet (UV) and vacuum ultraviolet (VUV) excitations [1][2][3][4]. BaMgAl10O17 crystallises into β -alumina crystal structure with P63/mmc space group.…”

“…It also requires control of crystallite size, morphology, texture, and lattice defects as well as nanosized crystallites. , It has been shown that SCS allows fulfillment of all of these requirements for a wide variety of systems. Among the recently studied nanophosphors produced by SCS, we can mention Tb-doped ZrO 2 , Eu-doped ZrO 2 , EuVO 4 , Y 2 SiO 5 , BaMgAl 10 O 17 , Sr 2.91 V 2 O 8 , Ba 3 Y 2 (BO 3 ) 4 , Sr 3 Y 2 (BO 3 ) 4 , Mn-activated ZnGa 2 O 4 , and Eu- and Dy-doped BaAl x O y . The SCS-derived nanophosphors usually have microstructure of type A or B (Figure ) and crystalline size from several nanometers to several tens of nanometers.…”

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.

We report on the photoluminescent properties of Ba 0.9 Eu 0.1 MgAl 10 O 17 (BAM) phosphors in correlation with the host crystalline structures. The phosphors were synthesized by citrate sol-gel process, followed by a sintering and a reduction step, both at elevated temperatures. We found that the phosphors were amorphous when sintered at temperatures below 900 °C. At 1000 °C, the crystalline structure was mainly that of BaAl 2 O 4 phase. The BaMgAl 10 O 17 phase appeared at 1100 °C, and became dominant with increasing temperature. At 1300 °C, the BaAl 2 O 4 phase almost disappeared, and only BaMgAl 10 O 17 features were found. The luminescent characteristics of the phosphors were closely related to the structures of the host lattice. Under the same reduction conditions, the phosphors sintered at 1000 °C showed the emission of both Eu 3+ and Eu 2+ . For the phosphors sintered at higher temperatures, the main features were originated from the emission of Eu 2+ . We additionally observed the increase of emission intensity and the broadening of emission spectra with increasing reduction temperature.
