A wavelength converting element (), typically for a LED (), is provided, comprising luminescent particles () dispersed in a matrix () comprising crosslinked polysiloxane. Crosslinked polysiloxanes are temperature stable, typically up to temperatures above 300&#xb0; C., meaning that they are stable under normal operating conditions of light emitting diodes. Further, crosslinked polysiloxanes are stable towards exposure to light, meaning that they will not degrade/discolor as a consequence of high intensity light exposure. The polymeric wavelength converter can easily be shaped in different forms. This may lead to better outcoupling of the light from a LED-converter system.
