摘要

在本报告中，采用一种简单、低成本和有效的方法来制备高度单分散的胶体。利用聚甲基丙烯酸甲酯上的化学缩合反应制备了ZnS量子点/SiO2光子材料。所获得的结果显示出1.47nm间距的回音廊发射模式。此外，ZnS量子点的发射受到球形微腔的调制。此外，利用模间距和腔尺寸之间的关系计算出球形腔尺寸，结果为11.86m。

Synthesis and characterization of ZnS/SiO2 photonic dots

In this report, a facile, low-cost, and effective method has been employed to produce highly monodisperse colloids photonic materials ZnS QDs/SiO2 were fabricated using chemical condensation reactions on poly-methyl methacrylate. The obtained results exhibit whispering gallery emission modes with 1.47nm spacing. In addition, the emission from ZnS QDs was modulated by a spherical microcavity. Furthermore, the spherical cavity dimension was calculated using the relation between modes spacing and cavity dimension and found to be 11.86 m.
