We carried out a careful photoluminescence (PL) and thermoluminescence (TL) characterization of nominally pure monoclinic ZrO2 nanopowders subject to oxidative vs reductive annealing (up to 1450°C). The two kinds of studied zirconia (sol-gel-prepared vs commercial powder) exhibited virtually identic...
