Tunable Emission Properties of Ir(III)-Complex Embedded Silica Colloids with Layer-by-Layer Multilayered Shells |
| 초록 |
We synthesized a Ir(III)-complex embedded silica colloids by modified Stöber method. The size of silica colloids was controlled by changing the concentration of ammonium hydroxide and emission wavelength was tuned by changing in the cyclometalated ligands of Ir(III)-complexes. Using Layer-by-Layer deposition, CBZ-PAA/PAH multilayer films were formed on the silica colloids and emission intensity of silica colloids was enhanced by effective energy transfer from these multilayer shells. In addition, we also designed multiple colored phosphorescent-emitting colloids through the control of energy transfer efficiency between multilayered shells (Ir-PEI complexes) to core Ir(III)-embedded silica colloids. Modulation of energy transfer efficiency in 3D structure was performed by changing in the thickness of multilayered shells. |
