In this work, we investigated the nonlinear optical properties of monolayer MoS2 and WS2 modulated by defect engineering via chemical treatment. The results demonstrate that two-photon luminescence (TPL) absorption (TPA) coefficient were remarkably improved after repair sulfur vacancies for both WS2. After treatment, nonradiative relaxation path dominant in pristine is significantly alleviated, resulting enhanced TPL. Our work affords an effective way to tailor absorption, sulfur-based...
Herein, we report a novel optical glass material, fluoroaluminate (AlF3) glass, with excellent transmittance from ultraviolet to infrared wavelength ranges, which provides more options for application in devices. Based on its performance, the phase-type Fresnel zone plate (FZP) by femtosecond (fs) laser-inscribed lithography is achieved, induces refractive index change fs-laser tailoring. The realization of fabrication inside can benefit performance AlF3 glass. Compared traditional...
Flat bands and electron correlation in moir\'e lattices give rise to many exotic phases, including Mott insulators, superconductivity, topological states. Within the first band, integer fractional quantum anomalous Hall effects have been observed twisted bilayer MoTe2 (tMoTe2) at one hole doping per unit cell, respectively. When second band is fully doped, spin insulator has also reported tMoTe2 a certain twist angle. Exotic states together with ferromagnetic (FM) high can potentially exist...
