New fluorine-derivatives of 3-hydroxyflavone (3HF) are synthesized. Their spectral luminescent properties are investigated. A range of plastic scintillators (PS), which contain fluorine-derivatives of 3-hydroxyflavone as the activation dopant, is obt

A new radiation-hard plastic scintillator (PS), based on polystyrene and activated with fluorinated 3-hydroxyflavone, is presented. The new scintillator has the light output half-attenuation dose equal to 11 Mrad, which is much more than a similar PS

Spectral and luminescence characteristics of three laser dyes incorporated into xerogel matrices preliminarily calcined under 700oC were studied in the spectral range of 600–700 nm. A stabilizing effect of these matrices on the dye molecules in the

In the present work the synthesis, structure and spectral properties of SiO2-matrices of different porosity (23%, 48% and 78%) doped by 4-N,N-dimethylamino-4′-N’-methyl-stilbazolium tosylate (DAST) are described for the first time. DAST does not

This study describes a new plastic scintillator for pulse shape n - γ discrimination. The scintillator contains two activation centers with different life spans. The first activator collects the singlet excitation energy of a polymer base, and the s
