.

(A) Absorption coefficient was calculated using GGA method within DFT for pure and rhodium doped hematite, (B) optical absorption of hematite compared with other DFT (a) and experimental results (b,c). The DFT results have been taken from Simone et al.49 and experimental data from the work of Gardner et al.50 & Marusak et al.51 (C) a percentage increase in absorption of rhodium doped hematite in the visible range
