Abstract: InAs-based nanocrystals can enable RoHS-compliant optoelectronic devices, but their photoluminescence efficiency needs improvement for practical applications. We report an optimized synthesis of InAs@ZnSe core@shell nanocrystals that allows to finely tune the ZnSe shell thickness up… read more here.

DOI: 10.1103/physrevb.102.035201
Abstract: Time-resolved photoluminescence and light-induced transient grating techniques were applied for temperature and excitation dependent internal quantum efficiency and carrier diffusion investigation in silicon-doped epilayer and AlxGa1-xN MQWs (x > 0.6). Decrease of photoluminescence efficiency at… read more here.
