Abstract
Bridgman grown CsPbBr3 single crystals have demonstrated γ-ray spectra with a high resolution, making them a highly promising competitor for the current benchmark room-temperature radiation detector Cd1−x Znx Te. However, CsPbBr3 crystal growth is a very slow process that oftentimes results in cracked ingots due to phase transitions from cubic to orthorhombic crystal systems. In this report, we demonstrate the stabilization of a room-temperature cubic phase in Cs(Pb1−x Snx )(Br3−y Cly ) solid solutions to overcome this issue. Cs(Pb0.75 Sn0.25 )(Br1.00 Cl2.00 ) was identified as the most promising composition and grown as a crack-free ingot using Bridgman growth in around one week.Graphical abstract:
