Comparison of the luminescence properties of phosphate-tungsten bronze and cerium doped phosphate-tungsten bronze [PDF]

Book of Proceedings, 2023
Phosphate-tungsten bronzes (PWBs) constantly attract a lot of attention owing to their interesting chemical, mechanical, and optical properties. Furthermore, tungsten bronzes as inert inorganic solids, exhibit interesting and useful electronic properties when rare-earth ions are incorporated into their structure. Cerium doped phosphate-tungsten bronze (

The structure and thermoelectric properties of tungsten bronze Ba6Ti2Nb8O30 [PDF]

Journal of Applied Physics, 2019
Tungsten bronze (TB) structured materials have attracted attention as possible thermoelectrics because of their complex crystal structure. In this work, a new thermoelectric ceramic with a tetragonal tungsten bronze (TB) structure, Ba6Ti2Nb8O30 (BTN), was prepared by the conventional mixed oxide route with some samples processed by Spark Plasma ...
