In the first part of the talk, we discuss the specificities of the bandgp properties of zinc oxyde.
Second, we review the last results available which concern the optical properties of quantum wells, quantum dots and microcavities based on it. A systematic comparison is made with GaN .
Third, we discuss the polariton laser issue and we show the potentialities of oxydes compared to nitrides.
Last we give some words concerning the realization of single photon sources using ZnO spherical quantum dots surface-passivated by MgO, and we compare this system with its challenger, namely CdS capped by ZnS.
