Luminescence conversion LED used in optical semiconductor components has LED chip emitting primary radiation in specified region which is partially or completely converted into longer wavelength radiation

摘要

A luminescence conversion LED has an LED chip emitting primary radiation in the region of 300-460 nm which is partially or completely converted into longer wavelength radiation using a luminescent material which is subjected to the primary radiation. Conversion is achieved with the aid of a luminescent material having an average particle size d50 in the region of 1-50, preferably 2-25 nm. An independent claim is also included for a process for the production of LEDs with nano-luminescent materials.
