Abstract

The present invention concerns an illumination system comprising radiation source that when operational emits radiation in wave length range below 280 nm to an emission element that comprises an assembly of oligo atomic metal clusters confined in molecular sieve for converting invisible radiation emitted by a radiation source at room temperature or an higher temperature to visible light and further a transparent envelope said illumination system.
