| 英文摘要 | A thin film of silicon-based nanobubbles was recently suggested that could block a fraction of the sun's radiation to alleviate the present climate crisis. But detailed information is limited to the composition, architecture, fabrication, and optical properties of the film. We examine here the optical response of Si nanobubbles in the range of 300-1000 nm to evaluate the feasibility using semi numerical solution of Maxwell's equations, following the Mie and finite-difference time-domain procedures. We analyzed a variety of bubble sizes, thicknesses, and configurations. The calculations yield resonance scattering spectra, intensities, and field distributions. We also analyzed some many-body effects using doublets of bubbles. We show, due to high valence electron density, silicon exhibits strong polarization/plasmonic resonance scattering and absorption enhancements over the geometrical factor, which afford lighter but more efficient interception with a wide band neutral density filtering across the relevant solar light spectrum. We show that it is sufficient to use a sub monolayer raft with similar to 0.75% coverage, consisting of thin (similar to 15 nm) but large silicon nanobubbles (similar to 550 nm diameter), to achieve 1.8% blockage of solar light with neutral density filtering, and similar to 0.78 mg/m(2) silicon, much less than the mass effective limit set earlier at 1.5 g/m(2). We evaluated solid counterpart nanoparticles, which may be produced in blowing/inflation procedures of molten silicon, as well as aging by including silicon oxide capping. The studies confirm the feasibility of a space bubble filtering raft, with insignificant imbalance of the correlated color temperature (CCT) and color rendering index characteristics of sunlight. |
