| 主权项 | 1. Surface-modified phosphor particles comprising luminescent particles which in turn comprise at least one luminescent compound that is (Ca,Sr,Ba)2SiO4 or other silicates, in each case individually or mixtures thereof with one or more activator ions, wherein both at least one metal, transition-metal or semimetal oxide layer and an organic coating are applied to the luminescent particles, and wherein the organic coating comprises at least one alkoxysilane, polyorganosilaxane or mixtures thereof. | ||
