... resulted in the evolution of gas at high reaction temperatures above 240°C. The presence of the gas decreased the residence time and induced the blueshift of the PL peak. FWHM of PL is an indirect ... controlling the size of the CdS NCs. The variation of the volume per- centage of OA from 10.5 to 51.2% and the variation of the residence time from 17 to 136 s facilitated th...
