Light-emitting structures based on colloidal quantum dots of cadmium sulphide having a high color rendering index

Light-emitting structures based on colloidal quantum dots of cadmium sulphide having a high color rendering index

Quantum dots created by colloidal synthesis (CQDs) were investigated. The paper shows how by changing the size and concentration of CQDs the emission spectrum of the structure with a color rendering index greater than 90 was achieved. Creation of the light- emitting structures involved spin-coating...

description Quantum dots created by colloidal synthesis (CQDs) were investigated. The paper shows how by changing the size and concentration of CQDs the emission spectrum of the structure with a color rendering index greater than 90 was achieved. Creation of the light- emitting structures involved spin-coating of CdS CQDs onto the glass substrate and consequent high-vacuum annealing. Methods allowing the increase of the emission intensity to achieve better approximation of the radiation spectra shape of white LEDs' spectra.
