Summary: In order to achieve chip-level integration of controllable nanoscale light sources, the authors demonstrate a novel approach of heterogeneously integrating electroluminescent carbon nanotubes with photonic circuits. By back-gating the nanotubes, electrical control of the emission is achieved with high on-off ratio and strong enhancement in the telecommunication band. The use of nanographene as a low-loss material enables efficient coupling without compromising optical quality. This study provides a versatile method for integrated photonic circuits.

Summary: The study demonstrates that bias tunable aspectral response can be achieved by coupling a HgTe NC array with a plasmonic resonator. The observed blueshift arises from the interplay between hopping transport and inhomogeneous absorption due to the presence of the photonic structure. This research expands the realm of existing NC-based devices and lays the foundation for light modulators.

Summary: A dual-narrowband absorber consisting of graphene and a photonic crystal heterostructure is proposed and analyzed in the terahertz band. The absorption is greatly enhanced due to the excitation of optical Tamm states at the interfaces. The absorber exhibits narrow full width at half maximum (FWHM) absorption peaks that can be tuned by controlling the graphene Fermi energy and photonic crystal periods, and it also maintains high absorption over a wide incident angle range for both TE and TM polarization. The proposed absorber has potential applications in THz biosensors, filters, and switches.

Summary: To enhance the efficiency of a solar thermophoto-voltaic system, a nanolayered narrowband thermal emitter is proposed. The thermal emitter consists of alternating layers of a-SiNx and a-SiNyOz deposited on a polished silicon substrate covered by metallic molybdenum. The fabricated emitters exhibit good narrowband absorption at the designed emission wavelength and can be tuned by changing the thickness of the multilayers. The simulated solar thermophotovoltaic system efficiency reaches 28.9% based on the proposed emitter.

Summary: Thermal camouflage technology, with advances in infrared detection technology, is becoming increasingly important in modern military warfare. However, there are still challenges in developing tunable emitters with infrared camouflage and thermal management properties. This work presents a tunable infrared selective emitter (TISE) made of multilayer Al and Ge2Sb2Te5 (GST). The TISE can achieve low emissivity in the atmospheric window and high emissivity in the non-atmospheric window, demonstrating excellent infrared camouflage and thermal management properties. It can switch between camouflage and non-camouflage states by adjusting the crystallization fraction of GST. The TISE also shows great insensitivity to obliquely incident light. It is expected to support further exploration in the fields of infrared camouflage, thermal imaging, and plasmonic metamaterial applications.

Summary: In this study, a new type of structural color material is reported, which is achieved by filling polystyrene nanospheres into silver brochosomes. The color is originated from the enhanced electromagnetic resonances of the polystyrene nanospheres by the surrounding metallic nanobowls. The color can be modified by tuning the diameter of the polystyrene nanospheres through plasma etching treatment. This material exhibits promising applications in the field of structural colors due to its simple fabrication process and easy processability.

Summary: In this study, it was discovered that aromatic molecules can be directly converted into nanostructures containing graphene quantum dots (GQDs) using cryogenic electron-beam writing, resulting in even red fluorescence emission. The photoluminescence intensity of the product can be easily controlled by adjusting the electron-beam exposure dose. Experimental analysis revealed a carbonization and graphitization process of the aromatic molecules during e-beam irradiation. This one-step method for production and patterning of GQDs enables their application in highly integrated and compact optoelectronic devices.

Summary: Personal thermal management is a topic of growing interest due to climate anomalies and the focus on physical health. A colored textile based on woven cloth is developed, which has superior passive radiative heating capability while maintaining aesthetics. By coating infrared transparent inorganic nanoparticles on MXene-decorated cotton, the textile achieves desired color, high near-infrared absorptivity, low mid-infrared emissivity, and wearability. Thermal tests demonstrate significant temperature increases compared to pure cottons, making this textile suitable for energy conservation and multi-spectral camouflage.

Summary: We report self-organized periodic nanostructures on amorphous silicon thin films induced by femtosecond laser oxidation. We investigate the dependence of structural periodicity on the thickness of silicon films and the substrate materials. The results show that the period of self-organized nanostructures is close to the laser wavelength and independent of substrates when the silicon film is 200 nm. However, for a 50 nm thick silicon film, the period of nanostructures is much shorter than the laser wavelength and dependent on the substrates. Furthermore, we demonstrate that the formation of periodic nanostructures is dominated by quasi-cylindrical waves in thick silicon films and by slab waveguide modes in thin silicon films, which is supported by numerical simulations.
