Abstract

New series of oxides, $Li_xPb_{1-2x}^{II}M^{III}_xO (M = Al, Fe):$ , for 0< x \leq 0.33 adopting the yellow PbO structure have been synthesized by solid state reaction of $Li_2CO_3, Pb(NO_3)_2$ and $Al_2O_3/FeC_2O_4·2H_2O$ in air at $650-680 ^o C$. Optical absorption spectra reveal systematic increase/decrease of electronic band gap Eg for the Al/Fe members as compared to the parent yellow PbO. Partial deintercalation of lithium occurs under oxidative conditions $(Br_2/CH_3CN)$ with both the series.
