Abstract
A small volume optoelectronic chip contains an LED chip with a diamond having nitrogen-vacancy centers embedded therein. The LED chip generates light having a first wavelength, and the diamond with nitrogen-vacancy centers generates light having a second wavelength after excitement with light having the first wavelength. The diamond may also be on or adjacent the LED.
