Fig. 2: Diffuse reflectance spectra.
From: Charge transfer emission between π- and 4f-orbitals in a trivalent europium complex
Diffuse reflectance spectra of solid state Eu-MCPO (black solid line) and Gd-MCPO (black broken line). The weak absorption peak at approximately 465 nm corresponds to the 7F0 → 5D2 transition for Eu(III).
