Abstract
The effect of photo-and thermoactivation of the CdSe cores of colloidal quantum dots (CQDs) on the luminescent properties of the CdSe@CdS CQDs formed on them has been studied. It has been established that an optimum combination of the action of UV light and heat on the CdSe cores has a favorable effect on the luminescent characteristics of the CdSe@CdS CQDs formed on them, noticeably increasing the quantum yield of luminescence, narrowing the spectral emission band, and enhancing their stability.
