“…The second morphology is spherical polycrystalline aggregates or semi-spherical particles appeared in C75G25 and C50G50 samples due to radiating growth from the center [16]. The third kind is platelet morphology with large pores and high surface area which was observed in C25G75 and C0G100 samples and is probably due to the evolution of large amount of gases as by-products [16].…”

“…Typically, products of combustion synthesis are highly reactive and pure and contain minimum level of impurities. Currently, several researchers have employed the combustion method to synthesize a variety of oxide ceramic powders with good success [13,14]. In previous studies, we have reported a successful synthesis of inorganic materials via chemical combustion along with their complete characterizations and demonstrated their potential for application in environment remediation [15][16][17][18].…”

A rapid, safe and simple technique for the production of high purity strontium oxide powders via a chemical combustion process is reported. The combustion reactions were performed to optimize the fuel to oxidizer ratios in the reaction mixtures required to obtain pure SrO powders by varying the molar ratio of chemical precursors and the temperature. The synthesized powders were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectrometry, infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, and N 2 -physisorption measurements. The results indicate that crystalline SrO was obtained using a 1:1 strontium nitrate: urea molar ratio at 1000°C after 5 minutes. In addition, high-purity, homogeneous and crystalline SrO powders were easily produced in a short time via a chemical combustion process.

“…Actually, there are a lot of scientific literature on the II-VI semiconductor material zinc oxide (ZnO) produced by researchers dedicated to the physical optical study in all the world, because the ZnO has singular and extraordinary physical and chemical properties: presents a wide direct band gap of 3.37 eV at room temperature [1] and has bonding energy of 60 meV that makes ZnO very apt for exciton-based applications [2]. However, such properties make to the ZnOa very versatile material ideal for working in conjunction with other materials.…”

After the synthesis process all the samples were annealed at 900˚C by 24 h. The pure ZnO, ZnO: Ce 3+ and ZnO/Cu 2+ + Ce 3 powders were structurally characterized using X-ray diffraction (XRD) technique, the XRD patterns showed that for either undoped and doped with the Cu 2+ ion both exhibited the hexagonal wurtzite ZnO crystalline structure, also the diffraction peaks of both samples types showed a little change toward lesser angles. The morphology and particle size of the samples were observed by means of a scanner electron microscopy (SEM); from SEM imagen is observed that the crystallites of the samples are agglomerated forming cage-like hollow structures caused by the combustion process. The cage-like structures have approximate size of 800 nm. In addition, the photoluminescence of pure ZnO, ZnO: Ce 3+ and ZnO: Cu 2+ + Ce 3+ compounds was measurement as a function of Cu 2+ ion concentration under a excitation wavelength of 378 nm in the UV region. As an important result, it is observed that by Auger phenomena of non-radiative recombination, the UV emission of the ZnO is quenching.
