Title
(EN) III-V semiconductor core-heteroshell nanocrystals
Abstract
(EN)

Provided is a core/multishell semiconductor nanocrystal including a core and multiple shells, which exhibits a type-I band offset and high photoluminescence quantum yield providing a bright tunable emission covering the visible range from about 400 nm to NIR over 1600 nm.
