Giant light extraction enhancement of medical imaging scintillation materials using biologically inspired integrated nanostructures

Abstract

We have utilized biologically inspired (bio-inspired), moth-eye nanostructures and further improved this biomimetic structure to enhance the scintillator materials external quantum efficiency significantly. As a proof of concept, we have demonstrated very high light output efficiency enhancement for ${\mathrm{Lu}}_2{\mathrm{SiO}}_5\text{:}{\mathrm{Ce}}^{3+}$ (LSO:Ce) film in large area, the X-ray mammographic instrument was employed to demonstrate the light output enhancement of the ${\mathrm{Lu}}_2{\mathrm{SiO}}_5\text{:}\mathrm{Ce}$ thin film with biologically inspired (bio-inspired) moth-eye-like nanophotonic structures. Our work could be extended to other thin film scintillator materials and is promising to achieve lower patient dose, higher resolution images of human organs and even smaller scale medical imaging.
