Photographs of the sample and the IR heater. (a) The BaBrCl:0.5% Eu sample sealed in a silica glass tube. (b) The sample surrounded by the NiO–YSZ light-absorber plates and suspended in a larger silica glass tube to prevent spills in case the sealed tube fractures. (c) The quartz lamp heater with the sample installed right next to it. The bottom of the sample was not heated by the lamp, in order to provide a solid–liquid interface during the measurements. |
