About this Research Topic
This research topic features submitted papers from the EMRS Spring 2022 Symposium on Novel Materials for Radiation Detectors. The topic focusses on the synthesis, characterization and application of perovskite and organic materials as radiation detectors. These materials have seen a large increase in interest for radiation detection in recent years. The topic will cover the latest trends and performance of these materials for ionising radiation detection.
This topic will focus on the development and characterization of perovskite and organic materials for use as radiation detectors, and will identify new trends in these materials for both direct and indirect detection of ionising radiation. These relatively new materials offer particular advantages over established technologies, such as their use as large area and potentially low cost devices, their high radiation sensitivity and detection efficiency, and synthesis using solution-based methods. Both perovskite and organic materials have the potential to disrupt traditional semiconductor radiation detectors, with a wide range of customizable electronic and optical properties suitable for different modalities of radiation detectors. The scope of the special topic reflects that of the EMRS Spring 2022 Symposium, and will cover the following themes:
Perovskites: There have been rapid recent advances in perovskite materials for use as radiation sensors, with many different materials within the perovskite family now under investigation. With the advantage of low cost solution-based growth, both inorganic perovskites and hybrid organic-metal perovskites show considerable potential for X-ray and gamma detection. The symposium will cover perovskite materials with the tradition ABX3 composition, and also double-perovskites and ‘lead free’ materials. The development and characterization of perovskite single crystals, thick films and nanoparticles will be discussed, in the context of ionising radiation detection applications.
Organic Materials: The development of organic materials for electronic applications has seen a dramatic and sustained growth over the last decade. Organic materials possess a unique set of characteristics and capabilities which are well suited for ionising radiation detection, including tissue-equivalence for X-ray/photon dosimetry applications, and applications in fast neutron detection due to their hydrogenic content.
Growth/synthesis of new materials for ionising radiation sensors:
- Solution growth methods for perovskite and organic crystals
- Thick film and polycrystalline perovskite and organic materials
- Synthesis of perovskite nanoparticles
- Printing processes for large area perovskite and organic detectors
Material characterization and radiation sensing properties:
- Optical dynamics in radioluminescence and scintillation
- Radiation induced defects and trapping
- Charge transport and defect characterization
- Electrical characterization, contact and interface studies
- Radiation sensitivity in photocurrent and pulsed mode
- Materials modelling of electrical and charge transport properties
- Photoconversion processes in direct detection systems
