Abstract
Nanosized cadmium sulfide particles (quantum dots; QDs) were synthesized in ethylacetate and (poly)methylmethacrylate by the reaction between cadmium trifluoroacetate and H2S formed by the hydrolysis of thioacetamide (TAA). The stability of colloid solutions was provided by thioacetamide complexes on the surface of CdS particles. The Cd(II): TAA ratios and the constants of the reaction between cadmium trifluoroacetate and thioacetamide in the (CF3COO)2Cd · nH2O-TAA-P system, where TAA was thioacetamide and P was ethylacetate or (poly)methylmethacrylate, were determined by spectrometric methods. The size of CdS particles and the rate of their formation were estimated. The data on the effect of synthesis conditions on the spectral luminescent properties of CdS in a (poly)methylmethacrylate matrix were presented.
