Sol-gel materials for photonic applications: Dissertation

Juha Rantala

Research output: ThesisDissertationMonograph


Sol-gel technology is employed for the fabrication of diffractive elements and organic light emitting devices, and hybrid sol-gel materials are used for the first time for electron beam lithography and direct writing of surface relief diffractive elements. These materials can be tailored to have a sufficient response to electron radiation and ultra-violet light and to form submicrometer-sized features. The technology has a potential for cost-effective mass-production of micro and integrated optics. A novel method for the fabrication of organic light emitting micro-pixels by means of photopatternable dielectric hybrid sol-gel material is also demonstrated.
