对Schott商业和实验CdSSe掺杂玻璃进行的光致发光和吸收实验揭示了存在一对接近电子能带的窄电子态。根据对发光随半导体球尺寸变化的研究，我们初步将其解释为表面态。对吸收光谱的仔细分析似乎证实了这一结论。
Photoluminescence and absorption experiments performed on Schott commercial and experimental CdSSe-doped glasses reveal the existence of a pair of narrow electronic states close to the electronic bands. According to a study of the luminescence as a function of the size of the semiconductor spheres, we tentatively interpret them as surface states. A careful analysis of the absorption spectra seems to corroborate this conclusion.
