An object of the present invention is to solve an environmental problem caused by containing cadmium ions by the invention of a cadmium-free quantum dot. Kind Code: A1 Abstract: Some silicon-containing surface-modifying ligands can be used to increase the affinity of semiconductor nanoparticles (quantum dots) for polysiloxanes, and quantum dots dispersed in a polysiloxane matrix are used in light emitting devices. Thus, the emission spectrum of such a device can be changed. The polysiloxane is, for example, R-Si (CH3) 2-O- (Si (CH3) 2-O) n-Si (CH3) 3. [Selection diagram] Fig. 1 |
