| Popis: | Cubic phase CdSe nanocrystals were prepared through a novel ultrasonic activation double-phase approach at room temperature. The band-edge emissions with the band centered at 452, 478, 496, and 511 nm and the surface state charge carrier recombination emissions from around 520 to 590 nm were observed for the CdSe with diameters of 1.4, 1.7, 1.9 and 2.1 nm, respectively. Those fluorescence emission spectra calculated chromaticity coordinates fall well within the white, white, green and yellowish green colors with quantum yield of about 1–2%. |
