Thermal behavior of the YAG precursor prepared by sol–gel combustion process

Spectroscopic properties of nano-sized cerium-doped lutetium aluminum garnet phosphors via sol–gel combustion process

“…Its key feature is that the heat required to drive the chemical reaction and accomplish the compound synthesis is supplied by the reaction itself and not by an external source. In the past several years, we have synthesized nanoscaled YAG powders by this method, using citric acid as the fuel [23][24][25][26]. Recently, we have also successively fabricated transparent polycrystalline LuAG:Ce ceramics by solid-state reaction using high-purity oxides or nanoscaled LuAG:Ce powders synthesized by co-precipitation method [27][28].…”

Structural and luminescence investigation on gadolinium gallium garnet nanocrystalline powders prepared by solution combustion synthesis

“…Such materials are also very efficient in infrared (IR)-to-visible up-conversion with possible applications as IR-sensitive phosphors, biological labels and up-converting materials. The appearance of many different synthesis techniques like pulsed laser deposition [12], solution combustion (propellant) [13][14][15][16][17], sol-gel [18], sol-gel combustion [19], wet chemical [20] or co-precipitation [21,22] synthesis enables the production of different nanophosphors with improved characteristics. One of the advantages of these techniques is that nanocrystalline powders are obtained as a final product.…”

Synthesis of YAG powder by the modified sol–gel combustion method

“…The sharp weight loss appears at the range of 300-500 • C and tends to terminate at about 900 • C. The sharp exothermal peak at 440 • C in DSC curve accompanying the substantial weight loss in TG curve, results from the release of CO 2 due to the decomposition of excess citric acid and carboxylate [18]. So precalcination at 500 • C employed in our experiments can effectively remove the undecomposed organic components (citric acid and carboxylate) from the combustion-formed precursor powder.…”
