Abstract
Photoluminescence properties of Rb(La0.90Bi0.10)Ta2O7, Layered Perovskite compound, and its exfoliated form, (La0.90Bi0.10)Ta2O7 nanosheet were characterized. The excitation and emission peaks of Rb(La0.90Bi0.10)Ta2O7 were 305 nm and 553 nm, respectively. The emission peak of (La0.90Bi0.10)Ta2O7 nanosheets solution was at 524 nm when the sample was excited at 281 nm. (La0.90Bi0.10)Ta2O7 nanosheets are promising candidates for thin film inorganic EL or luminescence sheet to prevent counterfeiting currency.
