Defect-related versus excitonic visible light emission from ion beam synthesized Si nanocrystals in SiO2 [PDF]
, 1996 Two sources of room temperature visible luminescence are identified from SiO2 films containing ion beam synthesized Si nanocrystals. From a comparison of luminescence spectra and photoluminescence decay lifetime measurements between Xe + -implanted SiO2 ...

High Luminescence in Small Si/SiO2 Nanocrystals: A Theoretical Study [PDF]
, 2010 In recent years many experiments have demonstrated the possibility to achieve efficient photoluminescence from Si/SiO2 nanocrystals. While it is widely known that only a minor portions of the nanocrystals in the samples contribute to the observed ...

Superconducting parity effect across the Anderson limit [PDF]
, 2017 How small superconductors can be? For isolated nanoparticles subject to quantum size effects, P.W. Anderson conjectured in 1959 that superconductivity could only exist when the electronic level spacing $\delta$ is smaller than the superconducting gap ...

Giant suppression of Auger electron cooling in charged nanocrystals [PDF]
, 2007 This letter presents a detailed study of the electron relaxation lifetimes from the excited p-like state into the ground s-like state via Auger cooling in positively and negatively charged CdSe nanocrystals, where the dependence of Auger cooling rates on

Nanocrystals for enhancement of oral bioavailability of poorly water-soluble drugs
Asian Journal of Pharmaceutical Sciences, 2015 Nanocrystals, a carrier-free colloidal delivery system in nano-sized range, is an interesting approach for poorly soluble drugs. Nanocrystals provide special features including enhancement of saturation solubility, dissolution velocity and adhesiveness ...
