Luminescence characterization of chromium-containing -alumina Academic Article

abstract

• Characteristic photostimulated luminescence (fluorescence) in the visible range is reported from theta transition alumina prepared by using a variety of methods. The luminescence is associated with trace concentrations of chromium and can be intensified by intentional chromium doping. The luminescence from thetaalumina is similar to, albeit considerably weaker than, the Rline luminescence from alphaalumina. The thetaalumina spectrum is characterized by a doublet at 14575 and 14645 cm1 at 77 K and is blueshifted from the Rlines of alphaalumina by 150 cm1. The doublet is attributed to Cr3+ ions in octahedral coordination and can be used for phase identification in microstructural characterization.
