Scintillation and Inorganic Scintillators
2016This chapter introduces the basic definitions and gives the minimum necessary information about the phenomenon of scintillation and the mechanisms which have to be taken into account for the development of scintillation materials. It starts with an historical brief and describes the sequence of the processes leading to scintillation in a dielectric ...

Luminescence and scintillation characteristics of Gd3Al2Ga3O12:Ce3+ scintillators
Optical Materials, 2013Abstract Cerium-doped Gd3Al2Ga3O12 single crystals were grown by the Czochralski method with 1 at.% cerium. Absorption, luminescence and scintillation characteristics were investigated. The light yield and energy resolution were measured under 662 keV γ-ray excitation.

This work is an investigation of the Circinus H20 megamasers, especially the unusual rapid variability seen in their flux density. It has been previously hypothesized that this was due to interstellar scintillation and one of the aims of this study was to test this.

Liquid scintillators with advanced scintillation characteristics
Instruments and Experimental Techniques, 2010Results of studying the influence of the component composition of liquid scintillators on their scintillation properties are presented. The correlation between the energy resolution and the peak-to-valley ratio in β-ray spectra is discussed. Compositions of fire-safe scintillation systems with characteristics above the generally accepted standard are ...

A new scintillator for liquid scintillation counting
The International Journal of Applied Radiation and Isotopes, 1967Abstract This report describes the results of investigations carried out with a new scintillator: 2-(4′-t-Butylphenyl)-5-(4″-biphenylyl)-1,3,4-oxdiazole (Butyl-PBD). Counting efficiencies and background counts of variously quenched toluene and dioxane systems containing Butyl-PBD have been compared with similar systems containing PPO and DM-POPOP as ...

Scintillation Mechanisms in Inorganic Scintillators
2016Details of energy transfer phenomena and scintillation mechanisms in luminescent media excited by ionizing radiation are discussed in this chapter. The sequence of relaxation of electronic excitations is described: creation of electron-hole pairs, energy transfer to emitting centers of interest and quantum efficiency of these luminescence centers.

Scintillation response of organic and inorganic scintillators
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999Abstract A method to evaluate the scintillation response of organic and inorganic scintillators to different heavy ionizing particles is suggested. A function describing the rate of the energy consumed as fluorescence emission is derived, i.e., the differential response with respect to time.

Scintillation mechanism and efficiency of ternary scintillator thin films
IEEE Transactions on Nuclear Science, 2002The scintillation mechanism of ternary plastic scintillators, excited by ions, was studied in order to correlate the scintillation efficiency as a function of the thickness to the energy transfer process between the light emitters embedded in the polymer.

Journal of the Optical Society of America A, 2003
A formula to compute the index of stellar scintillation detected with a finite spectral bandpass and with arbitrary aperture is derived in the limit of weak perturbations. It also applies to differential scintillation (relative fluctuations of light intensity in a pair of apertures), where the effect of finite bandpass turns out to be significant.
