International audience; With their excellent energy resolution, efficiency, and intrinsic radio-purity, cryogenic calorimeters are primed for the search of neutrino-less double beta decay (0nDBD). The sensitivity of these devices could be further increased by discriminating the dominant alpha background from the expected beta-like signal. The CUPID-0 collaboration aims at demonstrating that the measurement of the scintillation light produced by the absorber crystals allows for particle identification and, thus, for a complete rejection of the alpha background. The CUPID-0 detector, assembled in 2016 and now in data-taking, consists of 26 Zn$^{82}$ Se scintillating calorimeters for about $2 \times 10^{25}$ 0nDBD emitters. In this contribution we present the preliminary results obtained with the detector and the perspectives for a next generation project.
