Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of preparing a synchronized piezoelectric and luminescence material, the method comprising: 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, wherein the synchronized piezoelectric and luminescence material has an emission wavelength of 200 nm to 1,500 nm and a polarization of 0.1 μC/cm 2 to 100 μC/cm 2 . 2. The method of claim 1 , wherein the method includes: mixing the solution (a) and the solution (b); and adding the solution (c) into the resultant mixture to be mixed with each other. 3. The method of claim 1 , wherein the method includes: mixing the solution (a) and the solution (c); and adding the solution (b) into the resultant mixture to be mixed with each other. 4. The method of claim 1 , wherein the ligand in the solution (b) derives from a fluoride resin and has a structure substituted with H, OH, SH, SSOR, or COOH, wherein R is a hydrogen atom, a deuterium atom, a halogen atom, a cyano group, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms.
