The solid state reaction between Zn(CH3COO)2 andH2C2O4 under isothermal condition was studied by TG.The reaction was described by two steps.Their kinetic expressions were obtained by treating the fractionα of conversion with different mechanism functions g(α ).The first step was carried out wit...

We present a facile route for the synthesis of water-soluble Cu–Cd–Zn–S/ZnS core/shell quantum dots (QDs) by simple pH regulation. The PL spectra of Cu–Cd–Zn–S/ZnS core/shell quantum dots can cover the whole visible light region in the case of only two ratios of Cu/Cd/Zn. ...
