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. 1. A synchronized piezoelectric and luminescence material comprising:a core layer including light-emitting particles; anda shell layer which is attached onto a surface of the core layer and includes ligands having a piezoelectric property.2. The synchronized piezoelectric and luminescence material of claim 1 , wherein the light-emitting particles are surrounded by the plurality of ligands claim 1 , andsome or all of the ligands are ligands having the piezoelectric property.3. The synchronized piezoelectric and luminescence material of claim 1 , wherein the ligand having the piezoelectric property is attached onto the surface of the core layer through a ligand exchange.5.
