a UV–Vis absorption response of the La0.7Ca0.3MnO3 (LCMO) nanorods synthesized by hydrothermal method under different alkalinity conditions. b The variation of (αhv)2 absorption versus hv (photon energy) for the different samples (N10, N15, N20, K10, K15, and K20). N (or K) means the NaOH (or KOH) mineralizer, 10 (or 15, 20) for the NaOH (or KOH) concentration. Reproduced with permission of [80]
