Abstract

The invention provides a process for the production of a light converter comprising a siloxane polymer matrix with light converter nano particles embedded therein, the process comprising (a) mixing (i) light converter nano particles having an outer surface grafted with grafting ligands and (ii) curable siloxane polymers, and (b) curing the curable siloxane polymers, thereby producing the light converter; wherein the grafting ligands comprise siloxane grafting ligands having x1 Si backbone elements, wherein at least one Si backbone element of each siloxane grafting ligand comprises a side group having a grafting functionality; wherein the curable siloxane polymers have y1 Si backbone elements; and wherein x1 is at least 20, wherein y1 is at least 2, and wherein x1/y1≥0.8.
