In this report, we have used three

In this report, we have used three Se-ODE precursors at the temperature 160 oC, 180 oC, and 240 oC to investigate the effect of Se precursor on the characterization of the CdSe NCs. The name of the samples is called A160, A180, and A240, respectively. Their UV-vis absorption and PL spectra are shown in Figure 2. We observed a red shift as reaction continued with all samples. If the injection Se precursor at a higher temperature, the reaction of CdSe growth went even faster. The absorption peak of NCs CdSe shift from 573 nm to 630 nm after 1 min when injected the higher heating Se-ODE precursors, respectively. Because more precursors were used to form the nuclei in the early stages but with heating Se-ODE at 200 oC, 220 oC, 240 oC reactivity of Se becomes badly it shows in Figure …its PL only reach 582 nm to 625 nm and the FWHM decreased after 3min and it was narrow with A180 between 19nm 27 nm and broad with A200. A220 and A160. This result reactivity of Se-ODE 180 is effected to the high quality of CdSe NCs. was between 19 nm and 36 nm. That it to say, a large number of nuclei in the early stage.

In this report, we have used three Se-ODE precursors at the temperature 160 oC, the oC, 180 and 240 ºc to investigate the effect of Se precursor on the characterization of the CdSe NCs. The name of the A160, A180 is called samples, and A240, respectively. Their UV-vis absorption and PL spectra are shown in Figure 2. We observed a red shift as reaction continued with all samples. If the injection Se precursor at a higher temperature, the reaction of CdSe growth went even faster. The absorption peak of NCs CdSe shift from 573 nm to 630 nm after 1 min when injected the higher heating Se-ODE precursors, respectively. Because more precursors were used to form the nuclei in the early stages but with heating Se-ODE at the oC 200, 220, 240 he became oC the oC of the Se becomes badly it shows in Figure ... its PL only reach 582 nm to 625 nm and the FWHM decreased after 3 min and it was narrow with A180 between 19nm 27 nm and broad with A200.

In this report, WE HAVE USED Se-ODE three precursors at the temperature of 160 ° C, 180 °, and 240 ° C to Investigate the Effect of Se precursor on the characterization of the CdSe NCS. The name of the samples is gọi A160, A180, and A240, respectively. Their UV-Vis Absorption and PL spectra Shown in Figure 2. We are a red shift Observed as reaction continued with all samples. If the injection Se precursor at a Higher temperature, the reaction of CdSe thậm Went Faster growth. The Absorption peak of 573 nm NCS CdSe shift from 630 nm to 1 min sau khi injected the Higher heating Se-ODE precursors, respectively. Because more precursors used to form the nuclei Were in the early stages but with heating at 200 ° C Se-ODE, 220 ° C, 240 ° C reactivity of Se Becomes badly ... it shows in Figure nó only PL 582 nm to 625 nm Reach and the FWHM decreased after 3min and it was narrow with 27 nm and 19nm giữa A180 with A200 broad. A220 and A160. This result reactivity of Se-ODE 180 is EffectedDate to the high quality of CdSe NCS. was the between 19 nm and 36 nm. That it to say, a large number of nuclei in the early stage.
