was carried out in a microemulsion system, in which AM aqueous solution was the continue phase and p-methylphenylene was the dispersed phase using SPAN-60 and TWEEN-80 as surfactants, respectively......
:Eu3+nanocrystals,the CdTe:Eu3+nanocrystals were coated with SiO2 and the core-shell SiO2-coated CdTe:Eu3+nanocrystals(CdTe:Eu3+@SiO2) were prepared via microemulsion method.TEM results show that CdTe......
were prepared respectively via the formation of hydrolysis of tetraethyl orthosilicate (TEOS) with the synchronous modification of amino functional group in water-in-oil microemulsion. The diameter.... Synthesis of nanosize silica in a nonionic water-in-oil microemulsion: Effects of the water/surfactant molar ratio and ammonia concentration [J].

. The microemulsion was mixed rapidly, and after 5 min of equilibration, one drop (~0.05 mL) of hydrazine hydrate (9 mol/L N2H4×xH2O, Aldrich Chemical Co.) was added as a reducing agent. After nanosized water droplets were formed while stirring, TIP was added into the stirred microemulsion. NH4OH was injected into the microemulsion to accelerate the condensation reaction of metal alkoxide precursors. Reverse......
the preparation methods of ZrO2 nanoparticles from microemulsion[1-13]. However, the prices of raw materials and organic solvents such as cyclohexane and heptane are comparatively high, or the proportion... Ceramic Society, 1999, 19: 2593-2603.

process [4-5], hydrothermal process[6-7], microemulsion approach[8-9]. For example, XU et al[10] synthesized nanoparticles by combustion method, SHAP and PILLAI[11] prepared the precursor of CoFe2O4 by microemulsion approach, and these precursors were then calcined to give CoFe2O4 nanoparticles. In our laboratory, the CoFe2O4 nanoparticles were synthesized by using a new reverse microemulsion......
