We show that the rf-sputtering technique is suitable for the fabrication of high-quality structures based on glass. We present recent results regarding: A) 1D photonic crystals allowing $Er^{3+}$ luminescence enhancement; B) disordered 1D photonic structures for broad-band filters and light harvesting devices; C) 1D microcavities, embedding a poly-laurylmethacrylate layer activated with {CdSe}@$Cd_{0.5}Zn_{0.5}S$ quantum dots, allowing coherent emission; D) $Er^{3+}$-activated $SiO_{2}$ - $P_{2}O_{5}$ - $HfO_{2}$ - $Al_{2}O_{3}$ - $Na_{2}O$ planar waveguides. This research is performed in the framework of the projects COST MP1401 (2014--2018), PAS-CNR (2014--2016), ERANet-LAC RECOLA (2017--2019), MAECI PLESC bilateral project between South Africa and Italy, MaDEleNA PAT projects.
