Photoluminescence of QD-PVA Film for Displays
2018 IEEE International Conference on Electron Devices and Solid State Circuits (EDSSC)（2018）
Abstract
We reported for the first time a method based on surface-modification of core/shell QDs (CdSe/CdS/ZnS) has shown its excellent dispersibility, colloidal stability, and high photoluminescence quantum yield which was dispersed in Polyvinyl Acetate (PVA) aqueous solution. Different transmitted spectrum of QD-PVA film with varies concentration of QDs, R/G ratio, and thicknesses have been shown. The QD-PVA film used as down-converters for back-lighting in liquid-crystal displays may improve color gamut, and improve the feature of water and oxygen resistance.
