From: Barium Chemosensors with Dry-Phase Fluorescence for Neutrinoless Double Beta Decay

Measured response of dry barium-chelated vs. unchelated microscope slides excited at 365 nm under fluorescence microscope. Each error bar represents the 1σ spread if intensities within a single slide, and each point represents an independently prepared slide. A clear enhancement of the “on” state relative to the “off” state is visible.
