Abstract
This dissertation examines erbium-doped micro and nanostructures in-depth, with a focus on optical properties and fabrication techniques. It investigates nanothermometry, emphasizing the stoichiometric control possible in these materials, and demonstrates ratiometric temperature measurement at the nanoscale. The research achieves significant results in trapping erbium-containing nanocrystals using optical tweezers and nanoaperture trapping techniques, establishing their capabilities as single-photon sources. The study goes on to describe the fabrication of erbium-doped silica microcavities and thin films using the sol-gel method, revealing their potential in creating microdisks that support low-threshold lasing.
