There is provided a method of preparing a synchronized piezoelectric and luminescence material. The method includes mixing a solution (a) including light-emitting particles or precursors thereof and a solution (b) including ligands having a piezoelectric property in a polar solvent; and optionally, mixing a solution (c) including ligands having a piezoelectric property in an antisolvent together with the solution (a) and the solution (b), if necessary.

Method of synthesizing synchronized piezoelectric and luminescent material with piezoelectric ligands and light-emitting particles

A synchronized piezoelectric and luminescence (SPL) material includes a core layer including light-emitting particles and a shell layer which is attached onto a surface of the core layer and includes ligands having a piezoelectric property. Therefore, a piezoelectric property and a luminescent property can be simultaneously implemented using a single SPL material in which piezoelectric ligands and light-emitting particles are chemically coupled.

The present invention relates to thermally and chemically stable quantum dots encapsulated with functional polymeric ligands, a thermally stable quantum dot optical film using the encapsulated quantum dots, and a method for preparing the encapsulated quantum dots. The coating of the surface of the quantum dots with the polymer stabilizes the quantum dots and improves the durability and dispersibility of the quantum dot optical film, achieving markedly improved efficiency of photoluminescent quantum dot devices. Therefore, it is anticipated that the present invention will pave the way for practical use of quantum dots in a variety of light-emitting applications, particularly in high power light-emitting sources, to find commercial application in various fields, including displays, bioimaging, lightings, and photovoltaic cells.
