Abstract In response to the urgent demand for windows with multi‐mode self‐calibrated temperature feedback operating over a wide range in extreme environments, herein, Pr 3+ –Er co‐doped Y 2 Zr O 7 (YZO) transparent ceramics were developed. After annealing treatment remove defects, these exhibit high transparency and temperature‐dependent wide‐range photoluminescence, which in‐line transmittance is up 77.8% at 760 nm (theoretical limit 78%), luminescence band spans blue red. Furthermore,...
Transparent MgAl2O4 spinel nanoceramics have been sintered at relatively low-temperature (500–700°C) under high pressure (2–5GPa) using a hydrostatic press with high-temperature-calcined nanopowders. The morphology, nanostructure, optical property, and density of ceramics were analyzed by scanning electron microscopy, transmission UV-VIS-IR spectrum, Archimedes draining method. average grain size (<100nm for all samples sintered) depends on the sintering temperature. are highly...
Abstract A detailed investigation of planetary ball‐milling for coarsened AlON powder was carried out. Our results showed that the weight ratios milling ball‐to‐powder, revolution rate and time have significant impacts on microscopic morphology, particle size distribution average powder. The process mechanism were analyzed, outcome our study can be used to optimize complicated method by controlling or adjusting at final stage ball‐milling. Sequentially, using fine uniform optimized with an...
We fabricate transparent MgAl2O4 nano-ceramics, which are composed of 40 nm grains, by sintering under high pressure and low temperatures. Analysis the grain size, differential strains, yield strength porosity obtained from transmission electron microscopy x-ray diffraction indicates that pores at boundary triple junctions can retard migration thus prevent growth. It is found relatively density for nano-ceramics produced low-temperature attributed mainly to large energy in exteriors. The...
We present a detailed theoretical study of the electronic transport properties monolayer graphene. The quantum and conductivities are calculated on basis usual momentum-balance equation derived from semiclassical Boltzmann equation. investigate carrier-impurity scattering in massless Dirac quasiparticle system. carrier interactions with remote background impurities considered, carrier--carrier screening is included within random phase approximation. dependence temperature also examined....
Abstract Using micro-sized aluminum powder (11 wt.%) and nano-sized Al 2 O 3 (89 with five different phase compositions, AlON powders were synthesized at temperatures in flowing-nitrogen atmosphere. Our results suggest that for starting materials low γ-Al /total ratio R (0 0.15), a calcination temperature of 1 750 °C is required to obtain single-phase AlON. This about 50 higher than other batches larger values (0.5, 0.85, 1.0). The fabricated from reactants high value this work show narrower...
