“…CdS NP synthesis: UV-visible absorption and fluorescence measurements Cd(CH 3 CO 2 ) 2 was used as a convenient source of Cd 2+ ions to form the CdS NP in DMSO [4,9]. The addition of Cd(CH 3 CO 2 ) 2 to 20 mL of DMSO results in the formation of a clear solution.…”

“…It is clear than the particles obtained by microwave heating present higher luminescence behavior than those obtained by colloidal method. The sharp luminescence of particles with cycling heating profiles is a dramatic example of the efficiency of the synthesis method and capping stabilizer in electronically protecting the structures from chemical degradation and size increase [Serrano et al, 2009;Ni et al, 2002].…”

“…This is due to free electron pairs in the carbonyl group, which stabilize semiconductor nanoparticles by electrostatic forces generated in the system, and it can also act as coordination agent in compounds with metallic atoms with free orbital. It has been reported the use of sodium citrate as chalcogenide nanoparticles stabilizer, with good results in optical and structural properties [Serrano et al, 2009;Vazquez et al, 2009].…”

Nanoparticles with PbS core of 12 nm and shell of approximately 3 nm were synthesized at PbS:ZnS ratios of 1.01:0.1 using Merca Ptopropionic Acid as stabilizing agent. PbS/ZnS nanoparticles present a dramatically increase of Photoluminescence intensity, confirming the confinement of the PbS core by increasing the Quantum Yield from 0.63 to 0.92 by the addition of the ZnS shell. In this case, the synthesis by microwave method allows obtaining nanoparticles with enhanced optical characteristics in shorter reaction time than those of nanoparticles synthesized by colloidal method.

“…It is therefore important, to enhance the application of ZnS nanoparticles, to develop a simple lowtemperature synthetic process to prepare the Mn 2+ -doped ZnS nanoparticles. 13), 14) In order to obtain nanoparticles, a low-temperature solution process is essential, as restriction of the particle growth rate is key to obtaining nanoparticles. Yang -doped ZnS nanoparticles by mixing an aqueous solution of manganese acetate and zinc acetate with the Na 2 S aqueous solution, and ¡-methacrylic acid was added to the aqueous solution of the metal salts to control the growth rate of the nanoparticles.…”

-doped ZnS nanoparticles showed PL characteristics when irradiated with an excitation light with a wavelength of 345 nm. Accordingly, a simple process to heat the mixture of the sulfide precipitate and ethylene glycol at 348 K enabled us to obtain a homogeneous transparent sol of Mn 2+ -doped ZnS nanoparticles with PL characteristics. According to the results of the chemical analysis of the molar fraction of Mn 2+ in the obtained precipitate (X Precipitate ) and the nanoparticles in the sols (X Nano ), the X Nano was less than that the X Precipitate as compared with the same X Solution . The Mn 2+ ions in the nanoparticles were dissolved in the solvent during the heat treatment since the solubility product of MnS was much larger than that of ZnS. As such, the dissolution-precipitate process played an important role in the formation of the sol.
