Abstract
Disclosed herein is an optical bonding composition that may be used in optical applications. An LED light source that utilizes the composition is also disclosed, as well as a method of making it. The LED light source may comprise: an LED die; an optical element optically coupled to the LED die; and a bonding layer comprising surface-modified metal oxide nanoparticles in an amorphous silicate network, the bonding layer bonding the LED die and the optical element together. Efficiency of the LED light source may be increased when using an optical extractor as the optical element.
