The present invention relates to the use of light-converting, colloidal, doped semiconductor nanocrystals to provide a new generation of high performance, low cost monochromatic and white light sources based on LEDs.

Semiconductor nanocrystals used with LED sources

The present invention relates to low reabsorbing semiconductor nanocrystals having, simultaneously, an emission center core surrounded by at least one absorbing shell capable of absorbing blue or purple light and a protective exterior shell. The emission center core is capable of emitting at least one different wavelength range of light. The low reabsorbing semiconductor nanocrystals demonstrate an absorbance ratio greater than or equal to 10. These low reabsorbing semiconductor nanocrystals can be used in optical applications, some of which can include, for example, light-emitting diodes, solid-state-lighting, solar cells, lasers, and biomedical tags.
