• synthesis of mesoporous hybrid materials by postsynthetic grafting to commercially available MCM-41. These individually dye-functionalized hybrid materials are mixed in variable ratios to furnish a powder capable of emitting white light with CIE chromaticity coordinates of x = 0.33, y = 0.33 and an external

• ; postsynthetic grafting; white light emission; Introduction The development of new efficient illumination materials has received increasing attention in the past years [1][2][3]. For the generation of white light the combination of a UV emitting light source and energy down converting phosphor emitting in the

• color temperature is possible. The synthesis of silica hybrid materials functionalized with a single dye was performed via postsynthetic grafting of commercially available MCM-41 according to literature procedures [12][13][17]. Therefore, the respective dye precursors 9, 10, and 8 at variable
