White LEDs with InP-ZnS quantum dots

Synthesis and application of InP/ZnS quantum dots (InP/ZnS QDs) were synthesized via non-coordinated system. The structural model of InP/ZnS QDs was completed by using composition analysis, absorption spectroscopy and emission spectroscopy. Furthermore, their applications as phosphors were investigated. The ZnS shell-growth temperature and time was controlled to obtain QDs with different sizes and the emission wavelength. Finally, a white LED was fabricated with InP/ZnS QDs.
