To optimize the optical properties of semiconductor nanoplatelets, simple routes to add high-quality shells are needed. We demonstrate uniform growth of CdS shells on CdSe nanoplatelets at 300 °C, overcoming limitations of previous low-temperature syntheses. We obtain core/shell nanoplatelets with spectrally narrow (20 nm) and efficient emission for shells up to 4 nm thick.
为了优化半导体纳米片的光学性质，需要有添加高质量壳层的简单方法。我们展示了在300°C下在CdSe纳米片上均匀生长CdS壳层的过程，克服了以往低温合成的局限性。我们获得了核/壳纳米片，其壳层厚度达4nm时发射光谱窄（20nm）且高效。
