The invention relates to novel phosphor mixtures comprising three or more silicate phosphors. The invention furthermore relates to the use of these mixtures in electronic and electro-optical devices, in particular in light-emitting diodes (LEDs) for backlighting applications. The invention furthermore relates to LEDs comprising the phosphors.

The invention relates to thermally tempered safety glass comprising an non-abrasive and porous SiOlayer which is stable during sintering and has a refractive index of between 1.25 and 1.40. The inventive safety glass can be obtained by coating standard soda-lime glass with an aqueous coating solution having a pH value of between 3 and 8 and containing between 0.5 and 5.0 wt. % of [SiO(OH)]particles (0&#x3c;y&#x3c;4 and 0&#x3c;x&#x3c;2) having a particle size of between 10 and 60 nm, and a surfactant mixture. The coated glass is then dried, thermally hardened at temperatures of at least 600&#xb0; C. for several minutes, and thermally tempered by a flow of air.

Aqueous coating solution having a pH of from 3 to 8, comprising 0.5-5.0% by weight of [SiO(OH)]particles, where 0&#x3c;y&#x3c;4 and 0&#x3c;x&#x3c;2, having a particle size of from 10 nm to 60 nm with a tolerance of &#xb1;10%, and from 0.005 to 0.5% by weight, based on the coating solution, of a surfactant mixture obtainable by hydrolytic polycondensation of tetraalkoxysilanes in an aqueous-alcoholic-ammoniacal medium at temperatures between 35&#xb0; C. and 80&#xb0; C., with subsequent removal of ammonia and alcohol from the resultant dispersion by steam distillation and subsequent addition of a surfactant mixture comprising 15-30% by weight of anionic surfactants, 5-15% by weight of nonionic surfactants and less than 5% by weight of amphoteric surfactants.
