A general framework for scintillation in nanophotonics [PDF]
, 2021 Bombardment of materials by high-energy particles (e.g., electrons, nuclei, X- and $\gamma$-ray photons) often leads to light emission, known generally as scintillation. Scintillation is ubiquitous and enjoys widespread applications in many areas such as medical imaging, X-ray non-destructive inspection, night vision, electron microscopy, and high ...

The Effects of Dissolved Methane upon Liquid Argon Scintillation Light [PDF]
, 2013 In this paper we report on measurements of the effects of dissolved methane upon argon scintillation light. We monitor the light yield from an alpha source held 20 cm from a cryogenic photomultiplier tube (PMT) assembly as methane is injected into a high-

Scintillations And Microlensing [PDF]
Symposium - International Astronomical Union, 1996 It is shown how the theory of scintillation may be applied to treat gravitational lensing. The theory is applied to microlensing by a system of N point masses. It is shown that scintillation theory reproduces a known result for the angular broadening due to multiple microlensing.

Characterizing Quantum-Dot-Doped Liquid Scintillator for Applications to Neutrino Detectors [PDF]
JINST 7 (2012) P07010, 2012 Liquid scintillator detectors are widely used in modern neutrino studies. The unique optical properties of semiconducting nanocrystals, known as quantum dots, offer intriguing possibilities for improving standard liquid scintillator, especially when combined with new photodetection technology. Quantum dots also provide a means to dope scintillator with

Simulating intergalactic quasar scintillation [PDF]
, 2013 Intergalactic scintillation of distant quasars is sensitive to free electrons and therefore complements Ly$\alpha$ absorption line experiments probing the neutral intergalactic medium (IGM). We present a new scheme to compute IGM refractive scintillation

Properties of new scintillator glasses and scintillating fibers [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1986 We present data on the light output and optical properties of new scintillation glasses. Data on light (? ? 2.6g/cm3) and heavy (? > 3.4g/cm3) glasses are presented. In addition, the performance of scintillating glass fibers fabricated using a new light glass is discussed.
