Hybrid wavelength converter, method for manufacturing same, and light emitting diode comprising same |
| abstract |
The present inventive concept relates to a hybrid wavelength converter including both a metal halide perovskite nanocrystal particles and non-perovskite-based quantum dots or non-perovskite-based phosphors converting a wavelength of light generated from an excitation light source to specific wavelengths, and a light-emitting device including the same. By including metal halide perovskite nanocrystal particles and non-perovskite quantum dots or non-perovskite phosphors in the dispersion medium, the hybrid wavelength converter according to the present inventive concept enables to make simultaneous wavelength conversion to red and green light, and to be optically stable and improved color purity and luminescence performance without changing the emission wavelength range even with a lower cadmium content than the conventional quantum dot wavelength converter. |
