SrAl2O4 :Eu2+, Dy3+ Long Afterglow Phosphors Prepared by Chemical Coprecipitation Method Yan Changhao1,QIU Guanming2,Dai Shaojun3,Zhang Shengqu4,Sun Yanbin5,Zhang Ming1 (1.Department of Chemistry..., Shenyang 110006, China) Abstract:SrAl2 O4: Eu2+ , Dy3+ long afterglow phosphors were prepared by chemical coprecipitation method. Ammonium carbonate and ammonium hydrogen carbonate were used......
coprecipitation methods: composite carbonate process and composite hydroxide method. The effects of calcination temperature of precursors on the physical properties and electrochemical performance...; coprecipitation method; precursor; spinel 1 Introduction Since energy density is related to cell voltage and capacity, both high voltage and large capacity of positive materials are necessary[1-2......
coprecipitation method has the inherent disadvantage of inhomogeneity of resultant composition, especially when pH values of the precipitations of different initial ingredients are highly discrepant.... A novel modified coprecipitation method, called microwave-assisted peroxyl-complex coprecipitation (MAPCC), was put forward in this study. Effects of adding H2O2 and properties of alumina-doped yttria......
Synthesis of monodispersed nanometer-sized YAG powders by a modified coprecipitation method潘林,秦晓英,李地,张建摘 要:Nanometer-sized yttrium aluminum garnet (YAG) powders were synthesized by using the coprecipitation method with ammo- nium hydrogen carbonate as a precipitant. The results indicated that an extremely loose YAG precursor was obtained when iodine......
Synthesis of monodispersed nanometer-sized YAG powders by a modified coprecipitation method ZHANG Jian1,QIN Xiaoying1,LI Di1,PAN Lin1 (1.Key Laboratory of Materials Physics,Institute of Solid State Physics Chinese,Academy of Sciences,Hefei 230031,China) Abstract:Nanometer-sized yttrium aluminum garnet (YAG) powders were synthesized by using the coprecipitation method with ammo-nium hydrogen......
were studied. It is found that, compared with coprecipitation method, the sol-gel target has more homogeneous components and larger density and grain size, thus the higher insulator-metal transition...: La0.72Ca0.28MnO3; target; thin film; sol-gel method; coprecipitation method 1 Introduction Mixed-valence manganese oxides La1-xAxMnO3 (A represents the divalent alkaline earth) have been widely studied......
of Ce0.33Zr0.55(LaNdY)0.12O2 mixed oxides was realized via a facile and scalable approach,namely,sulfateaided coprecipitation method was labelled as CZ-S.Sulfate ion(SO42-) was added into raw solution in the form of sulfuric acid and acted as coordination agent.The control sample was prepared by conventional coprecipitation method without sulfuric acid added and labelled as CZ.The promotion effect......
