Summary: This study demonstrates the near-infrared light-driven reversible and dynamic photonic bandgap modulation of soft photonic crystal through the integration of core-shell upconversion nanoparticles and a novel molecular photoswitch. The intensity ratio of UV/vis luminescence emitted by the UCNPs can be controlled by changing the excitation power, leading to red-shift and blue-shift of the photonic reflection. This work provides new insights into the fabrication of 3D photonic nanostructures with tailorable functionalities for soft-matter photonics and integrated communication technologies.

Summary: We demonstrate the effect of spin-momentum locking on upconversion photoluminescence emitted from rare-earth doped nanocrystals coupled to a phase-gradient dielectric metasurface. Different directionalities for left and right circular polarized light are observed, which can be attributed to the photonic Rashba effect that leads to a spin-dependent splitting of emitted light in momentum space.

Summary: To meet the requirements of data-intensive computing in the data-explosive era, researchers have extensively investigated brain-inspired neuromorphic computing for the past decade. However, challenges in integrating synaptic and neuronal devices in a single chip due to incompatible preparation processes have limited energy efficiency and scalability. Therefore, the development of a reconfigurable device with synaptic and neuronal functions in a single chip using the same materials and structures is highly desired. In this study, a reconfigurable hardware platform based on the polarization effect of 2D alpha-In2Se3 was designed, which can switch between emulating synapse and mimicking neuron. The application of this proof-of-concept device on a spiking neural network demonstrated its powerful learning ability and efficiency.

Summary: The rapid development of NIR spectroscopic techniques has led to the discovery of novel luminescent materials as broadband NIR light sources. Conventional phosphors powered by electricity may aggravate the energy demands. In this study, Ga2O3:Cr3+ nanophosphors are reported to emit broadband NIR light under mechanical action through self recoverable mechanoluminescence (ML). The ML intensity and profile can be deliberately tuned through crystal-site engineering. Highly tunable light emission in the range of 650-1,100 nm is achieved by controlling the dopant concentration of In3+ and Yb3+ co-doping. These findings contribute to the library of sustainable NIR light sources and offer new possibilities for advanced sensing and spectroscopy studies.
