Abstract
Nanocrystalline ZrO2:Nd3+ was synthesised using gel-combustion method and characterized systematically using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Through this route we can stabilize metastable tetragonal phase at 500 °C through addition of 1 mol % Nd3+ which is technologically more important. Optical characterization of the sample was done using photoluminescence (PL) and photoacoustic spectroscopy (PAS). PL studies shows an intense and optimum stimulated emission cross section of 1065 nm peak corresponding to 4F3/2 → 4I11/2 which and thus it can be a probable laser material. PAS is used to investigate electronic absorption of Nd3 in zirconia. Various covalency parameters like nephelauxetic ratio (β), covalency factor (b1/2) and Sinha parameter (δ) were evaluated for pure oxide powder and as well as for Nd3+ doped zirconia.
