高度发光的CdSeS纳米晶（量子效率高达85%），表现出从红到蓝的可调谐发光特性，带边窄（FWHM = 34 nm），通过在高温下向Cd前体溶液中一步加入Se和S源混合物来合成，并成功地将所得纳米晶体嵌入传统OLED结构中，以产生光谱清洁和窄的电致发光在光致发光光谱的相同位置处发射。
Highly luminescent CdSeS nanocrystals (quantum efficiency up to 85%), showing tunable luminescence properties from red to blue region with narrow band edge (FWHM = 34 nm), were synthesized by one-step addition of Se and S source mixture into the Cd precursor solution at elevated temperature, and the resulting nanocrystals were successfully embedded in a traditional OLED structure to give spectrally clean and narrow electroluminescence emission at identical positions of the photoluminescence spectrum.
