The achievement of structural color has shown advantages in large-gamut, high-saturation, high-brightness, and high-resolution. While a large number plasmonic/dielectric nanostructures have been developed for color, the previous approaches fail to match all above criterion simultaneously. Herein we utilize Si metasurface demonstrate an all-in-one solution color. Due intrinsic material loss, conventional metasurfaces only broadband reflection small gamut 78% sRGB. Once they are combined with...
Coherent ultraviolet light is important for applications in environmental and life sciences. However, direct lasing constrained by the fabrication challenge operation cost. Herein, we present a strategy indirect generation of deep-ultraviolet through tandem upconversion process. A core-shell-shell nanoparticle developed to achieve emission at 290 nm excitation telecommunication wavelength range 1550 nm. The ultralarge anti-Stokes shift 1260 (~3.5 eV) stems from combination distinct processes...
The applications of TiO 2 metasurfaces are extended from static planar visible photonics to dynamic devices and photochemistry.
Mechanical stretching has been an effective way to achieve widely tunable optical response in artificial nanostructures. However, the typical stretchable devices produce exactly reverse effects for two orthogonal linear polarizations, significantly hindering their practical applications many emerging systems. Herein, we demonstrate approach a mechanically all-dielectric metasurface with polarization insensitivity and full-spectrum visible range from 450 650 nm. By embedding TiO2...
Abstract Structural color, which generates vivid colors via the geometrical arrangement of resonant nanostructures, can enhance recyclability and mechanical stability colors; structural have been intensively studied in recent years, owing to their high resolution, color purity, compared generated by dyes pigments. Dielectric materials, possess a suitably refractive index low loss visible range, are ideal materials for colors. However, static optical performances most impose restrictions on...
The development of multi-wavelength lasing, particularly with the wavelength tuning in a wide spectral range, is challenging but highly desirable for integrated photonic devices due to its dynamic switching functionality, high purity and contrast. Here, we propose general strategy, that relies on simultaneous design electronic states optical states, demonstrate dynamically switchable single-mode lasing spanning beyond record range (300 nm). This achieved through integrating reversely...
Acquiring real-time spectral information in point-of-care diagnosis, internet-of-thing, and other lab-on-chip applications require spectrometers with hetero-integration capability miniaturized feature. Compared to conventional semiconductors integrated by heteroepitaxy, solution-processable provide a much-flexible integration platform due their solution-processability, and, therefore, more suitable for the multi-material system. However, are usually incompatible micro-fabrication processes....
Lanthanide (Ln3+ )-based ultraviolet B (UVB) microlasers are highly desirable for diagnostics and phototherapy. Despite their progress, the potential applications of UVB strongly hindered by low optical gain, weak light confinements, poor device repeatability. Herein, a novel all-in-one approach to solve above limitations realize mass-manufactural is reported. The gain coefficient at 289 nm improved from two aspects, i.e., enhanced absorption via LiYbF4 :Tm(1mol%)@LiYbF4 @LiLuF4...
