论文摘要
我们报告了杂化光的合成，该杂交光的发射颗粒的直径在100至500 nm之间，包括紧凑的半导体CDSE/CDSE/CDS/CDZNS纳米晶体聚集物，由受控的纳米尺寸二氧化硅和金层包围。我们首先表征了与添加金纳米壳相对应的purcell衰减速率增强，这是粒径的函数，并与数值模拟的预测找到了良好的一致性。然后，我们表明与Förster共振能量转移相对应的贡献受到抑制。
We report on the synthesis of hybrid light emitting particles with a diameter ranging between 100 and 500 nm, consisting in a compact semiconductor CdSe/CdS/CdZnS nanocrystal aggregate encapsulated by a controlled nanometric size silica and gold layers. We first characterize the Purcell decay rate enhancement corresponding to the addition of the gold nanoshell as a function of the particle size and find a good agreement with the predictions of numerical simulations. Then, we show that the contribution corresponding to Förster resonance energy transfer is inhibited.
