Raman Spectroscopy Analysis of GS-CN at Different Annealing Temperatures #2173122 (License: Personal Use)

This figure displays five overlaid Raman spectra of graphitic carbon nitride (GS-CN) samples annealed at increasing temperatures (500°C to 700°C), plotted against wavenumber (cm⁻¹). Key features include the D-band (~1350 cm⁻¹), G-band (~1580 cm⁻¹), and 2D-band (~2700 cm⁻¹), where rising annealing temperature sharpens peaks and alters intensity ratios-suggesting improved crystallinity and reduced defect density. The black-to-green progression reflects enhanced graphitization and layer ordering.
