Silica-coated cadmium telluride quantum dots (CdTe@SiO₂) exhibit increased sensitivity to UV illumination within the 300–400 nm range, allowing long and efficient Stokes-shifted emissions with more than 300 nm of separation from the excitation source. In addition, the surface modification of water-soluble CdTe quantum dots promotes a better dispersibility in a non-polar solvent (chloroform), allowing the facile fabrication of a highly luminescent PMMA/CdTe@SiO₂ composite with uniformly distributed CdTe@SiO₂ clusters suitable for photonic applications.

二氧化硅涂层增强了CdTe量子点在非极性PMMA溶剂中的斯托克斯位移和分散性

涂有二氧化硅的碲化镉量子点（CdTe @ SiO ₂）对300-400 nm范围内的紫外线照射具有更高的灵敏度，允许长且有效的斯托克斯位移发射，与激发源的分离距离超过300 nm。此外，水溶性CdTe量子点的表面改性促进了其在非极性溶剂（氯仿）中的更好分散性，从而可以轻松制造具有均匀分布CdTe @ SiO ₂簇的高发光PMMA / CdTe @ SiO ₂复合材料适用于光子应用。
