CdS Quantum Dots Based Nano Light Emitting Device
2021
In the present research work CdS based quantum dots embedded in the Poly-Vinyl-Pyrrolidone (PVP) capping layer have been synthesized via a simple chemical method and CdS quantum dot operation nano Light-emitting device. The nanoparticles have been characterized using standard techniques to reveal their optical and structural properties. A Light-Emitting Device (LED) has been fabricated using the CdS quantum dots, and the Electro-Luminescence (EL) phenomenon has been analyzed for a range of applied voltage, at room temperature. The obtained emission characteristics are almost linear with voltage, which indicates that CdS nano-dots are suitable for the light-emitting device.
