Micro grid mode resonance based artificial microstructure. a Schematic key steps involved in MG@hm-C(CN)3 synthesis. Inset: digital camera images of a bare nanoporous template (white) sample and a MG@hm-C(CN)3 sample (black). b Self-assembly of MG@hm-C(CN)3 nanosheets on nanoporous templates to form artificial microstructure (Scale bar, 150 nm). c Top-view (Scale bar, 1 μm) and d cross-sectional (Scale bar, 200 nm) SEM images of the MG@hm-C(CN)3. e Experimental absorption spectra measured by an integrated sphere in the visible and near-infrared range. MG represents the sample of nanoporous anodic aluminum oxide membrane (AAM), hm-C(CN)3 represents the sample of hm-C(CN)3 bulk material, MG@hm-C(CN)3 represents the sample of hm-C(CN)3 nanosheets incorporated into AAM, respectively
