Description
Lei Zhou and colleagues design a glow material for body imaging in a 2026 study. Organic afterglow materials keep glowing after light stops, but most need ultraviolet light and glow at short wavelengths. Their design twists a dopant molecule to lower its energy levels while keeping it compatible with host materials.
Doped into benzophenone, the material could be charged by light up to 700 nanometers, deep in the red range. Its afterglow reached 725 nanometers in the near-infrared, lasting about 67.82 milliseconds. The team used it for imaging free of background autofluorescence, the body's own glow.
