The features of visible dielectric thin-film luminescence under UV irradiation are discussed for single layers with a particular high-index/low-index couple, HfO<sub>2</sub>/SiO<sub>2</sub>. We exploit those results in an attempt to understand the proper luminescence of three different mirror stacks in terms of both luminescence efficiency and angular emission.
