1-D Photonic crystals were fabricated by sol-gel route. The cavities are constituted of an Eu3+-doped TiO2 active layer inserted between two Bragg mirrors, fabricated by stacking alternately undoped TiO2 and SiO2 sol-gel thin films. Transmission measurement and luminescence spectroscopy at different angles of the incident and observed light was employed to characterize the spectroscopic feature in the visible region of the sample.

Abstract
1-D Photonic crystals were fabricated by sol-gel route. The cavities are constituted of an Eu3+-doped TiO2 active layer inserted between two Bragg mirrors, fabricated by stacking alternately undoped TiO2 and SiO2 sol-gel thin films. Transmission measurement and luminescence spectroscopy at different angles of the incident and observed light was employed to characterize the spectroscopic feature in the visible region of the sample.File in questo prodotto:
