Abstract
We report on a series of fluorescent powders based on CdTe colloidal nanocrystals embedded into a protective NaCl matrix, which provide solid-state luminophores with emission colors covering the whole green to red spectral region of visible spectrum and enhanced fluorescence quantum yields comparing to the parent CdTe nanocrystals, unravelled by UV-vis absorption and diffuse reflectance measurements as well as by steady-state and time-resolved photoluminescence spectroscopy. Prototypes of hybrid light-emitting diodes of high color quality utilizing this kind of luminophores as a down-converting layer are demonstrated. © 2013 AIP Publishing LLC.
