From: Solvent-dependent self-assembly of two dimensional layered perovskite (C6H5CH2CH2NH3)2MCl4 (M = Cu, Mn) thin films in ambient humidity

Figure 5

Mn L2,3 edge absorption spectra taken in TEY mode at temperature lower than 44 K on (a) bulk single crystal Mn-PEA, (b) Mn-PEA thin film made from water solvent (Mn-PEA:H2O), (c) Mn-PEA thin film made from a mixed solvent of methanol and water (Mn-PEA:MeOH + H2O), (d) Mn-PEA thin film made from a methanol solvent (Mn-PEA:MeOH, RH > 50%). The inset figure in (a) shows the scattering geometry where two incidence angles (θ = 0°and 67.5°) are adopted. The figure in (e) shows how the water molecules in the air permeate into samples having two different growth morphology.
