The present invention relates to a method for producing a quantum dot-rare earth complex nanocrystal, a quantum dot-rare earth complex nanocrystal, and a light emitting device including the same. More particularly, a complex containing a rare earth element having characteristic light emission of rare earth ions is attached to the quantum dot. The present invention relates to a quantum dot-rare earth complex nanocrystal which simultaneously exhibits optical properties of two materials. In the method of preparing the quantum dot-rare earth complex nanocrystals according to the present invention, unlike the inefficient method of synthesizing the quantum dot and the rare earth complex, respectively, and then adding the two materials together, the reaction process is performed by mixing the respective precursors together. Since only necessary, the manufacturing method is simple, economical. The quantum dot-rare earth complex nanocrystals according to the present invention are not limited to Groups 2 to 6, but may also be applied to other semiconductor quantum dots such as Groups 3 and 5. In addition, since it is possible to emit light at various wavelengths of the entire visible light region in one nanoparticle it can be applied as a light emitting device. |
