A process of forming dichroic color filters on substrates, particularly image sensors, includes using a spin-on-glass process to form low and high refractive index layers. A mixture of titania and silica partially hydrolyzed and condensed sol-gel polymer suspension in the high refractive index layer and in the low refractive index layer has a partially hydrolyzed and condensed silica sol-gel polymer suspension are processed and to cause titania to phase change.
