nanoparticles were synthesized at lower temperature using Se powder as a selenium source and Na2S as a sulfur source instead of any pyrophoric organometallic precursors, respectively. The shell (CdS) can... that the application of CdSe/CdS nanoparticles as fluorescent probes in quantitative detection of protein is feasible. 2 Experimental 2.1 Reagents and chemicals Selenium (Se) powder (>99.5%, mass......

(Cd(NO3)2?4H2O), selenium powder (Se) and sodium sulfide (Na2S?9H2O) as raw materials. The effects of molar ratio of S to Se, pH value and hydrothermal reaction conditions on the structure, morphology... Experimental Raw materials for the preparation of Cd(S1-xSex) pigments were cadmium nitrate (Cd(NO3)2?4H2O, AR), selenium powder (Se, 99.9%) and sodium sulfide (Na2S?9H2O, AR). Na2S was dissolved......
