Revisiting the origin of green emission in Cs4PbBr6
An overview of recent debate about the origin of green emission in Cs4PbBr6 and/or CsPbBr3 is presented; several possibilities are discussed, including a defect-mediated event in Cs4PbBr6 or CsPbBr3 nano-inclusions embedded within Cs4PbBr6.

Cesium lead bromide semiconductor radiation detectors: crystal growth, detector performance and polarization
Large volume cesium lead bromide (CsPbBr3) perovskite semiconductor radiation detectors match the detection properties of CZT and TlBr but potentially at a lower cost and better stability.

Compositional engineering of multicomponent garnet scintillators: towards an ultra-accelerated scintillation response
A Czochralski-grown single crystal of GAGG:Ce,Mg allows for a high Ce dopant and Mg codopant concentration in the crystal, resulting in acceleration of scintillation decay down to several nanoseconds at the expense of light yield.

This special collection across Journal of Materials Chemistry C and Materials Advances is in memoriam of Prof. Richard T. Williams, who sadly passed away on July 5, 2021.
Prof. Richard Williams served as the Reynolds Professor of Physics at Wake Forest University until his passing in 2021. At Wake, Richard became internationally renowned for his pioneering contributions to the science of scintillators and ultrafast laser spectroscopy. His work has impacted many technological applications from energy and environment, to national security and healthcare. Prof. Williams also helped establish the PhD program at Wake Forest University where in the 1980s he mentored the first physics PhD graduate.
This special collection, which covers the topics he was most interested in, will honour Prof. Williams the scientist, the mentor and the colleague:
- Ultrafast spectroscopy
- Scintillators
- Optoelectronic devices
- Luminescent materials
- Quantum calculations
- Crystal growth
- Radiation detectors
