    The research on the preparation and characterization of transparent electrode carbon nanosheet based gelam woods bark doped with SnO2 - SbO2. Carbon nanosheet was prepared from gelam wood bark by microwave pyrolysis assisted hydrothermic reaction for 16 hours and then was heated in the microwave oven at 800 ˚C. Characterization of transparent electrodes were made using XRD, SEM, FTIR - Raman, impedance spectroscopy and UV-Visible spectrophotometry to study crystallography, surface morphology, functionality, electrical conductivity value, and optical properties. XRD analysis of carbon nanostructured crystals showed in simple cubic, i.e., 2θ = 26.87; 26.38, Sn metal in tetragonal crystal is formed at an angle 2θ = 28.587; 34.35; 51.99; 62.2 and Sb metal formed BCC cubic structures at angles 2θ = 40.34. SEM analysis show that the carbons have self-curling sheets which indicated that their surfaces have many defect. FTIR spectrograms indicate that CNS-O has several absorption peaks at for –OH stretch for free water and alcohol. At 2337 cm-1 was showed a carboxylic acid peaks and C=C stretch at 1627 cm-1. All carbonss exhibit abroad disorder-induced D-band (∼1330 cm-1) and in-plane vibrational G-band (∼1590 cm-1). Impedance spectroscopy shown that electrical conductivity of transparent electrode ranges from 1.26 x 10-7 Scm-1 – 5.03 x 10-7 Scm-1. Band gap values in the transparent electrode range from 2 eV - 3 eV which means they have conductor – semiconductor characters. The analysis of UV-Vis spectrophotometry showed the existence of maximum absorption in 400-530 nm and 550-700 nm.
