“…According to Ref. [22], R Te 4+ (6) = 0.97 Å, R Mn 4+ (6) = 0.53 Å, R Te 4+ (4) = 0.66 Å, R Mn 4+ (4) = 0.39 Å, where R (CN) represents the radius of ion and CN means coordination number. It shows that the radius of the Mn 4+ ion is smaller than that of the Te 4+ ion.…”

TeO2 single crystal has drawn much attention in recent years due to its excellent acousto‐optic (AO) performance in the field of spectral imaging and optical processing. The optical properties of TeO2 single crystal are critical for the fabrication of AO devices. To improve the optical properties of the TeO2 single crystal, Mn4+ ions were doped into the TeO2 lattice. Herein, bulk TeO2 single crystal and TeO2:0.02Mn4+ single crystal have been successfully grown by a Bridgman method. Compared with the TeO2 single crystal, a 30% transmittance increase was observed in the TeO2:0.02Mn4+ single crystal. Furthermore, the TeO2:0.02Mn4+ single crystal shows a smaller extinction coefficient (≤0.01) in the Vis–NIR region, indicating less optical loss. The bandgap energy of TeO2:0.02Mn4+ was broadened from 3.360 to 3.635 eV. In addition, TeO2:0.02Mn4+ single crystal exhibits a higher refractive index (about 2.244), which indicates that TeO2:0.02Mn4+ single crystal is a potential medium for high‐efficiency AO devices.

“…The control over their emission frequency by changing their crystal field has aroused widespread attention and found applications in scintillators, solar concentrators, temperature sensors, bioimaging, and luminescent lamps. [38][39][40][41] Based on the host material and sintering temperature, their emission can be tuned from the visible to the near-infrared region. In the present work, we report a strong room-temperature near-infrared emission of a tellurium-based double perovskite SrLaLiTeO 6 .…”

As an earth‐abundant, environment‐friendly and cost‐effective material, tetrahedrite Cu12Sb4S13 has attracted much attention in thermoelectrics. However, the thermoelectric (TE) performance of the pristine Cu12Sb4S13 (CSS) is mediocre, thereby much improvement is required. In this work, both the electronic and phonon transports of the CSS were engineered using Ga2Te3 as a dopant. The results indicate that dual substitutions of Ga for Cu and Te for Sb not only cause the enhancement of power factor (PF) via electronic band structure tuning, but also leads to a drop in both the electronic and lattice thermal conductivities. As a result, the total thermal conductivity (κ) decreases to 0.98 W/m K at 770 K, which is about 58% that of the pristine CSS, thus improving the TE performance with the highest ZT value increasing to 0.95 for (Cu12Sb4S13)0.9(Ga2Te3)0.1 at 773 K, 1.9 times that of the pristine CSS (∽0.5 at 770 K).This article is protected by copyright.
