The paper deals with the development of X-ray imaging composite detectors based on GAGG:Ce powders bound by the organic polysiloxane matrix. The luminescence intensity was improved through optimization of solid state reaction conditions and Ce concen

Y3-xGdxAl5O12:Ce (x = 0.6, 1.2, 1.8 in the melt) single crystals were grown from the melt by the Czochralski technique. XRD results shown that crystalline samples contain main garnet Y3-xGdxAl5O12 and additional Al2O3 and GdAlO3 phases. The maximal c

Peculiarities of cascade photon emission (CPE) and energy storage in M1−xPrxF2+x (M=Ca, Sr, Ba, x≈0.35) crystals were studied. The investigation of lattice parameters revealed that these solid solutions belong to the fluorite structure type with

High efficiency and reasonably fast decay time of NaI:Eu crystal point out the possibility of crystal application as scintillator. Modification of crystal properties by varying the activator concentration and heat treatment conditions enabled the ide

The spectral and kinetic parameters of LiCaAlF 6 :Pr and LiSrAlF 6 :Pr single crystals are studied at LHeT and room temperature (RT). Photon cascade emission (PCE), i.e., 1 S 0 → 1 I 6 and 3 P 0 → 3 H j , 3 F j transitions after Pr 3+ excitation

The radiation stability of the mixed crystals M1 − xRxF2 + x (M = Ca, Sr, Ba) depends on types of the alkaline-earth and rare-earth ions. Different to Eu- and Ce-containing systems, M1 − xPrxF2 + x solid solutions have a low radiation resistance,

A study of the radiation hardness of pure CsI crystals 30 cm long was performed with a uniformly absorbed dose of up to 14.3 krad. This study was initiated by the proposed upgrade of the end cap calorimeter of the Belle-II detector, using pure CsI cr
