(a) Normalized UV spectrum of as prepared stanene sheets (Sn, green), stanene sheets reduced using hydrazine (SnR, red) and subsequently oxidized using H2O2 (SnRO, black) and ε2 component, the imaginary part of the dielectric constant (Calculated, blue) using DFT. (b) Micro-Raman spectrum of as prepared stanene and oxidized sample using 532 nm Laser.
