Journal ArticleDOI
Enhancement of photoluminescence of monolayer transition metal dichalcogenide by subwavelength TiO2 grating
TL;DR: In this article , a combination structure of a gold film, titanium dioxide subwavelength gratings and monolayer transition metal dichalcogenide (TMDCs) is designed, which can greatly improve the photoluminescence efficiency of monolayers.
Journal ArticleDOI

TL;DR: In this paper , a 4-fold UPC enhancement was achieved in 5.5° twisted bilayer while conventional photoluminescence (PL) weakens by half, which provides a novel insight into a unique way that twisted angle affects UPC and light-matter interactions in 2D semiconductors.
Journal ArticleDOI

TL;DR: In this paper , a method for preparing ultra-thin wood acoustic diaphragms, less than 10 μm in thickness, relying on delignification, sulfonation, and densifying techniques, was introduced.
Proceedings ArticleDOI
Unidirectional propagation of surface plasmons under active control
TL;DR: In this article, a symmetric V-type slit array was proposed to tune the propagation direction of surface plasmon polaritons by external control of the polarization and/or the inclination angle of the incident light.
Journal ArticleDOI
Optical waveguide behavior of Se-doped and undoped CdS one-dimensional nanostructures using near-field optical microscopy
TL;DR: In this article, the optical waveguide behaviors of CdS and cdSxSe1−x nanostructures were studied using near-field optical microscopy and the photoluminescence (PL) spectra from nanoribbon emission was analyzed under different incident laser intensities.
