Abstract

Quantum rod (QR) on-chip LED is considered to be a cost-effective application method, but the thermal stability of the material is one of the prime concerns. Thermally induced photooxidation of nanomaterials, in a water-oxygen environment, is the main reason for the attenuation of its luminous intensity. In order to provide an optimized solution and improve device performance, we attempted to analyze the QR composition of CdSe/CdS and CdSe/CdS/ZnS QRs after decay using X-ray photoelectron spectroscopy (XPS) technique and studied the Attenuation mechanisms.
