Summary: This study presents the design of double-tapered optical-fibre arrays to increase the light output of thick light-emitting layers. It demonstrates the fabrication of large-scale pixel-dense X-ray and gamma-ray detector arrays. It also shows the possibility of high-resolution X-ray and gamma-ray imaging, as well as convenient monitoring of dynamic energy spectrum and dose rate using a hemispherical fibre array dosimeter.

Summary: This study demonstrates miniature photoactuators with high performance by embedding optical fibre taper in a polydimethylsiloxane/Au nanorod-graphene oxide photothermal film. The photoactuators show large bending angles, fast response, and low energy consumption, significantly exceeding the performance of state-of-the-art waveguide photoactuators.

Summary: Spatial resolution improvement has been achieved in the perovskite-based scintillation community using self-assembled perovskite nanosheets. The use of a polymer substrate provides flexibility and eliminates X-ray absorption. The assembly behavior of the nanosheets enables efficient energy transfer and mitigates reabsorption issues.
