Transparent ceramics (TCs) are promising for high-power (hp) white light-emitting diode (WLED) and laser (LD) lighting. However, comfortable warm light has not been achieved only using a single TC in hp-WLEDs/LDs. Herein, highly transparent Gd3Al4GaO12:Ce3+ (GAGG:Ce3+) TCs (transmittance, T = 55.9–80.2%) were prepared via solid-state reaction. Ce3+ as doped activator center grains plays positive role luminescence based on the microstructural investigations by scanning electron microscopy...

Pure BaMgSiO4:Eu2+ phosphor, prepared by a solid state reaction method under N2 atmosphere, exhibited strong green emission at 500 nm and weak 405 nm. Heat treatment NH3 atmosphere causes changes in the PL intensity: gradually decreases completely disappears after heat for 3 h, whereas new blue peak, centered 445 nm, appears becomes very strong. The results of analyses with electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), absorption fine structure (XAFS) suggest...

Abstract Tungsten carbide (WC)-based materials are widely considered as the hydrogen evolution reaction (HER) process catalysts due to their “Pt-like” electronic structure. Nonetheless, traditional powder electrodes have a high cost, and display problems related itself poor stability over operation time. This paper presented self-supported asymmetric porous ceramic electrode with WO 3− x whiskers formed in situ on walls of finger-like holes membrane surface, which was prepared by combining...

Developing an economical, durable, and efficient electrode that performs well at high current densities is capable of satisfying large-scale electrochemical hydrogen production highly demanded. A self-supported electrocatalytic "Pt-like" WC porous with open finger-like holes produced through industrial processes, a tightly bonded nitrogen-doped WC/W (WC-N/W) heterostructure formed in situ on the grains. The obtained WC-N/W manifests excellent durability stability under multi-step density...

Introducing carbon nanotubes (CNTs) into polymer or ceramic matrices has been a promising approach to obtain ultra-strong, extra-toughened materials as well multifunctional composites. Most of the previous work on CNT composites focused strengthening and toughening matrix at ambient conditions. However, so far there is lack information mechanical behavior these elevated temperature. Recently, single-walled CNTs were found undergo superplastic deformation with an appealing 280% elongation...
