Low activator concentration in upconversion phosphors has been a hindrance improving luminescence performance. Herein, we report an Er3+ doping as high 30 at. % the CaLuAlO4 host. The CaLuAlO4:Er3+ were prepared by traditional high-temperature solid-state method. Under excitation of 980 nm laser, optimal approaches 30% according to total integrated intensity red and green luminescence. This quenching is one order magnitude higher than that doped polycrystals. results obtained from...
Understanding the growth mechanisms of two-dimensional (2D) van der Waals (vdW) heterostructures is great importance in exploring their functionalities and device applications. A custom-built system integrating physical vapor deposition optical microscopy/Raman spectroscopy was employed to study dynamic processes 2D vdW situ. This allows us identify a new mode with distinctly different rate morphology from those conventional linear mode. We propose model that explains difference morphologies...
Abstract Recently, two-dimensional (2D) half-topological states, emerging in 2D half Weyl semimetals and Chern insulators, have attracted much attention due to their promising application spintronics. The fully spin-polarized topological nontrivial bands near the Fermi level will give rise spin-resolved bulk boundary charge currents, which might be beneficial charger transfer catalytic reactions. Taking room temperature ferromagnetic TiTe monolayer (T C ~ 964 K) as an example, hydrogen...
Cubic KNbO 3 and KTaO crystals are studied using the first‐principles VASP code. By employing local density approximation (LDA), GGA‐PBE, HSE06, lattice parameters optimized compared with available experimental data, best agreement is achieved HSE06. Electronic structures such as of states, band structures, charge‐density distribution discussed in detail for both crystals. The single‐crystal elastic constants, polycrystalline modulus, compressibility, Poisson's ratio, anisotropy factors...
Identifying the spatiotemporal change of groundwater table to precipitation at river basin scale can be important for regional water resource management. In this study, we proposed a method that combines singular value decomposition and cross-wavelet approaches analyze relationship between level dynamics precipitation. The was applied Naoli River Basin, Northeast China. Moreover, continuous wavelet using fast Fourier transform also used reveal clearly heavy results showed major mode divided...
The optical, electronic, and (photo) catalytic properties of covalent organic frameworks (COFs) are largely determined by their electronic structure and, specifically, Frontier conduction valence bands (VBs). In this work, we establish a transparent relationship between the periodic COFs orbital characteristics individual molecular building units, that is challenging to unravel through conventional solid-state calculations. As demonstration, applied our method five with distinct framework...

Two-dimensional transition metal dichalcogenides are highly promising platforms for memristive switching devices that seamlessly integrate computation and memory. Grain boundaries (GBs), an important micro-nanoscale structure, hold tremendous potential in memristors, but their role remains unclear due to random distribution, which hinders fabrication. Herein, we present a novel chemical vapor deposition approach synthesize star-shaped MoS
