A method for detecting the presence of or quantification of carbon black and/or black carbon in a sample or carrier medium. The method includes providing the sample or carrier medium without labelling or pre-treatment of the carbon black and/or black carbon particles; illuminating the sample or carrier medium at a temperature below 90&#xb0; C. by a pulsed light with a pulse duration below 500 femtoseconds, a repetition rate above 1 MHz with an average power below 20 mW, and a wavelength of a femtosecond laser pulse ranging from 700 to 1200 nm, to generate non-incandescence related light emission from the carbon black and/or black carbon particles; and analysis of the light emission.

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.
