Fig. 2: Optical chirality transfer modifies the luminescence of unstructured Eu2O3 films.
From: Controlling the symmetry of inorganic ionic nanofilms with optical chirality
a The relative intensity of the hypersensitive 7F2 luminescence peak decreases when illuminated with CP compared to linear light if the two interfaces (air-Eu2O3 and Eu2O3-polycarbonate in this case) have differential gradients. b, c The relative luminescence intensity decreases for CP light with input light power, but remains constant for LP light, owing to increasing optical chirality transfer in the former. d Numerical simulation of the change in C with distance from the input on passing through air, Eu2O3 and polycarbonate, using thicknesses of 300 nm (air), 150 nm (Eu2O3) and 350 nm (polycarbonate) for the three films. The magnitude of the IE terms for each interface is highlighted by the red arrow, and the net exchange of C, ΔIE is given.
