Session 1: New Detector Concepts
- Paul Sellin
A brief welcome to the NuSec Technical Workshop
Liquid scintillators consist of scintillating organic flours in organic solvents, and they have been used in radiation detection for many years. However, there are a number of advantages to using water as a solvent, and R&D of water-based liquid scintillators is becoming popular. Here, we have developed an alternative approach. We use quantum dots, or nano-crystals, as scintillating flours and...
Herein, we study a facile, toxic solvent-free surfactant-dependent mechanochemical synthesis of highly luminescent CsPbBr3 nanocrystals (NCs) and study their scintillation properties. A small amount of surfactant oleylamine (OAM) plays an important role in the two-step ball milling method to control the size and emission properties of the NCs. CsPbBr3 NCs capped with different amounts of...
In recent decades organic electronics have entered mainstream use in consumer electronics found in households around the world. I will present radiation sensors based on organic semiconductor technology, and in particular applications related to detection of hadronic radiation. This includes α, fast and thermal neutron radiation.
Organic semiconductor radiation detectors based on diode-like structures are well established. Here I present preliminary results on the potential for Organic Field Effect Transistors (OFET) as radiation detectors, where the nature of the OFET means that the signal is intrinsically amplified by the device.
