Stability of CdS nanocrystals in glass
Journal Article

· Physical Review B
We have measured and analyzed optical and x-ray-absorption spectra of CdS nanocrystals grown by solid-state reaction in a borosilicate glass, with average crystallite radii from 1.4 to 5 nm. The first (Cd-S) and second (Cd-Cd) neighbor distances are within 0.2% of the bulk values in all cases. We establish an upper bound for the interfacial tension of 0.15 N/m. Such low interface tension suggests that glass-embedded nanocrystals are inherently quite stable.
