Enhanced Thermoelectric Performance of SnTe-Based Materials Interface Engineering.
ACS Appl Mater Interfaces
October 2021
Interface engineering has been regarded as an effective strategy to improve thermoelectric (TE) performance by modulating electrical transport and enhancing phonon scattering. Herein, we develop a new interface engineering strategy in SnTe-based TE materials. We first use a one-step solvothermal method to synthesize SnTe powders decorated by SbTe nanoplates.

- Transparent glasses co-doped with Er3+, Tm3+, and Yb3+ were created using various alkaline earth fluorides (MgF2, CaF2, SrF2, BaF2) alongside nano-glass-ceramics with only BaF2.
- The study focused on the thermal stability and up-conversion emission properties, revealing that increasing the mass of bivalent cations shifts the UV cutoff band towards shorter wavelengths.
- Emission colors can be fine-tuned by altering the type of alkaline earth cations, particularly with Mg2+, while emission intensity is enhanced by transforming the glass through heating or increasing the amount of alkaline-earth fluorides.
Magnetic bioactive glass-ceramics (M GC) were prepared by doping apatite-wollastonite glass-ceramic (A-W GC) with Mn-Zn ferrite. The effect of different contents of Mn-Zn ferrite on the phase structure, magnetic property and bioactivity of A-W GC was investigated. X-ray powder diffraction results showed that A-W GC exhibited apatite, fluorapatite and wollastonite as the main phases.
