The photoluminescence and photostability of CdTe/CdS nanoparticles encapsulated in matrices of potassium dihydrogen orthophosphate, potassium bromide, calcium carbonate, and barium sulfate were studied. The greatest photostability was found for a composite with a monocrystalline KH2PO4 matrix. This stability is related to the hindered diffusion of oxygen to the implanted CdTe/CdS quantum dots.

无机盐基质的性质对 CdTe/CdS 量子点光学性质和光稳定性的影响

研究了封装在正磷酸二氢钾、溴化钾、碳酸钙和硫酸钡基质中的 CdTe/CdS 纳米颗粒的光致发光和光稳定性。发现具有单晶 KH2PO4 基体的复合材料具有最大的光稳定性。这种稳定性与氧气向注入的 CdTe/CdS 量子点的扩散受阻有关。
