Single-size CdS MSC-311 and MSC-322 prepared from one reaction mixture. Optical absorption spectra of CdS MSC-311 (blue trace) and MSC-322 (red trace), collected from a single preheated sample (~20 mg) (gray trace) after 20 h incubation at 4 and 60 °C, respectively. The dispersion solvent used was cyclohexane (3 mL). To prepare the sample, Cd(OA)₂ and SODE were mixed at room temperature with a 4 to 1 feed molar ratio and a S concentration of 30 mmol/kg in ODE; the mixture was heated up to 180 °C and was held for 20 min. For the optically transparent IP (gray trace) after stored at 4 °C for 20 h, single-size CdS MSC-311 developed, while at 60 °C for 20 h, single-size CdS MSC-322 evolved
