| 摘要 |
An optical composition is provided, comprising: —a polysilsesquioxane comprising repeating units of the formula [R—SiO1.5], wherein each R independently is hydrogen or a C1-C12 alkyl, aryl, alkene, arylene, alkenyl or alkoxy; —a polysiloxane, optionally substituted; and —particles dispersed in said polysiloxane. The polysilsesquioxane is able to disperse the particles in the polysiloxane, thus providing an optical composition comprising stably dispersed particles. The particles may be utilized to tune the refractive index or another optical property of the composition. Due to the low organics content, the composition has reduced risk of yellowing. The invention also relates to a bonding layer comprising an optical composition, an optical system comprising an optical composition, a method for preparing an optical composition and an optical system, respectively, and the use of a polysilsesquioxane for dispersing particles in a polysiloxane material. |
