We report the exotic photoluminescence (PL) behaviour of 3D topological insulator Bi<sub>2</sub>Te<sub>3</sub> single crystals grown by customized self-flux method and mechanically exfoliated few layers (18 ± 2 nm)/thin flakes obtained by standard scotch tape method from as grown Bi<sub>2</sub>Te<sub>3</sub> crystals. The experimental PL studies on bulk single crystal and mechanically exfoliated few layers of Bi<sub>2</sub>Te<sub>3</sub> evidenced a broad red emission in the visible region from ...[more]
