Surface Modification of Quantum dots for Solution-Processed Light Emitting Device |
| 초록 |
Quantum dots, semiconductor nanocrystals whose band gap can be manipulated by size control, is considered as a novel, promising material for future device applications in energy harvesting or display technologies. Many researches have been focused on device fabrication techniques, including solution-process, for its advantages on cost, convenience, and mass productivity. As most device fabrication by solution-process require phase differences of solvents between the conventional electron or hole transport layer materials which are dispersible in non-polar solvents, it is necessary for the quantum dots to be hydrophilic so that the sequential stacking of the device layers does not damage the preceding layer. However, most conventional quantum dots in the market, especially the ones with smaller diameter, are hydrophobic, that blue emitting quantum dot based device is difficult to be realized by solution-processing. In this presentation, we demonstrate surface modification of non-polar, blue emission quantum dots to water-stable state via phase transition, integration of the quantum dots into light-emitting device structure, and discuss the results. This work is supported by NRF of Korea, project number 2N40210. |
