Photoluminescence spectra and crystallization of θ-Al2O3 and α-Al2O3 from AlOOH-Fe(NO3)3 gels

Diphasic boehmite derived unseeded and seeded (by either α-Al2O3, α-Fe2O3, or Fe(NO3)3) alumina gel planar monoliths were examined by DTA, XRD and photoluminescence spectroscopy. Luminescence spectra enable sensitive monitoring of the Θ- and α-Al2O3 crystallization in heat-treated gels due to Cr3+ i...
