Transition metal dichalcogenide (TMD) monolayers provide a versatile platform for nanophotonic and optoelectronic devices due to their direct bandgap and strong excitonic response. However, tailoring their emission characteristics beyond the intrinsically narrow excitonic linewidth remains a key challenge. Here, we report a hybrid microcavity platform consisting of a WS2 monolayer coupled to polystyrene microspheres (PS-MSs) on a gold substrate under continuous-wave excitation. In this system, light emission can be tailored through the interplay between cavity-enhanced local electromagnetic fields and photoinduced changes in the microcavity optical response. At low excitation powers, the emission evolves from neutral-exciton-dominated to trion-dominated photoluminescence with a continuously tunable intensity ratio, reflecting changes in the relative exciton-trion contributions under laser excitation. At higher excitation powers, the system transitions to a broadband-emission regime, which is associated with irradiation-induced modifications of the microcavity optical properties and is further enhanced by the cavity configuration. The incorporation of the WS2 monolayer is correlated with enhanced broadband emission and improved performance under continuous-wave excitation, while also influencing the interfacial excitonic emission behavior. Furthermore, extending this approach to multiple-microsphere assemblies enables larger-area broadband emission, suggesting the potential scalability of this strategy toward planar white-light sources. These results establish a simple strategy for tailoring light emission in hybrid microcavities and provide insights into cavity-enhanced optical processes in coupled two-dimensional material-polymer systems, with potential applications in integrated photonic devices and broadband light sources.
Periodic orbits form the organizing skeleton of phase space in the three-body problem. While planar periodic solutions have been extensively studied, three-dimensional configurations remain comparatively scarce due to their increased complexity. Here we report the discovery of 10,059 three-dimensional periodic orbits of the three-body problem with two or three equal masses. The solutions span a diverse array of families, including spatial Lagrange, Sitnikov-like, Broucke-Hadjidemetriou-Hénon (BHH), and figure-8, as well as many sequences with more intricate topologies. Notably, approximately 20
The structure and composition of the lunar surface are heavily influenced by redox reactions driven by space weathering. Investigating these effects provides critical insights into the evolution of the lunar environment and identifies essential resources for future human exploration. However, this issue remains unexplored on the far side of the Moon due to technological constraints in lunar exploration. Here, we investigated the effect of space weathering on ilmenite retrieved by Chang’e-6 from the far side of the Moon for the first time. Compared with previous studies on lunar weathering rims, the results highlight several distinct features: (1) the relatively high area fraction of nanophase iron within the weathering rims; (2) formation of a pronounced nanoporous nanophase iron, accompanied by the weak signal of hydrogen and notable loss of oxygen (approximately 7 at
