Cu–Cd–Zn–S/ZnS core/shell quantum dot/polyvinyl alcohol flexible films for white light-emitting diodes

Abstract

We present a facile route for the synthesis of water-soluble Cu–Cd–Zn–S/ZnS core/shell quantum dots (QDs) by simple pH regulation.

Metal Nanoclusters/Polyvinyl Alcohol Composite Films as the Alternatives for Fabricating Remote-Type White Light-Emitting Diodes

“…Light-emitting nanomaterials, such as rare earth phosphors, colloidal quantum dots, and perovskites, embedder in resins, have been widely used as down-conversion layers in light-emitting diodes (LEDs) for illumination and display [1][2][3][4][5][6]. Despite the excellent performances in optical properties, these light-emitting materials still suffers from tedious production, high price and/or high toxicity [7][8][9].…”

Preparation of a Water‐Soluble ZnXCd1‐XS Quantum Dot Photocatalyst at Room Temperature Assisted by 3‐Mercaptopropionic Acid

“…[17][18][19][20][21][22][23][24][25][26] Unfortunately, the current scale of synthesis of water-soluble QDs ranges from a few milliliters to tens of milliliters, due to the limitations of reaction vessels such as three-port flasks and hydrothermal reactors, which also limit their practical application in water pollution treatment. [17,19,21,[27][28][29][30] In the preparation process of ZCS water-soluble quantum dots, cation and ligand coordinate to form precursor solution. Since Zn 2 + and Cd 2 + ions can stably exist in an alkaline environment, the precursor solution will be adjusted to alkaline by sodium hydroxide, and then sulfur source will be added.…”
