Where can I obtain solid-state UV or DRS characterization in our country?
LaMnO3 with K-substitution shows lower bandgap like that of LaSrMnO3 (LSMO). This material is black in colour and doesn't disperse in any solvent. Thus, only solid-state UV-Vis or DRS need to be done for its bandgap info. Also, the expected bandgap is below 1 eV which require one to go above 1200 nm wavelength range.
