Microwave-hydrothermal synthesis of ceramic powders

Experimental and theoretical studies on the enhanced photoluminescence activity of zinc sulfide with a capping agent

“…[15][16][17] Several reports in the literature describe the conditions required for PL. [18][19][20][21] In this paper, we present a comparative study of an intense and broad PL at room temperature for ZnS nanocrystals synthesized by an efficient microwave-assisted solvothermal method, [22][23][24] for different times to clarify the roles capping agents play in the enhanced PL activity of ZnS. The origin of the intense PL bands was investigated by electronic structure calculations carried out within the framework of ab initio periodic quantum-mechanical techniques.…”

Indium hydroxide nanocubes and microcubes obtained by microwave-assisted hydrothermal method

“…The use of microwave radiation in the hydrothermal system introduced by Komarneni et al [7] promotes the development of a new technique offering reaction kinetic enhancement, formation of materials with different morphologies, low synthesis temperature and reduced processing times. Recently, the MAH method has been successfully employed to obtain materials, such as ZnO [8], BaTiO 3 [9], CuO [10] and CeO 2 [11].…”

Hydrothermal synthesis of KNbO3 and NaNbO3 powders

“…7 In contrast, crystalline KNbO 3 powders can be synthesized by the hydrothermal method at temperatures below 200°C. 8,9 Unlike BaTiO 3 , the hydrothermal synthesis of KNbO 3 powders has not been extensively investigated. Komarneni and co-workers 8 reported that KNbO 3 could be synthesized at 194°C by reacting Nb 2 O 5 in a solution containing 3 M OH − and 9 M K + while Uchida et al 10 reported using 3 M KOH at 250°C.…”
