It is established that the most optimal in set of parameters are derivatives of diaryloxazole and oxadiazole, which contain branched alkyl substituents. Using the activator 2,5-bis(4-tertbutylphenyl)oxazole-1,3 PS with a n/γ-discrimination factor FOM = 1.52 and mechanical properties at the standard PS level was obtained. A series of 3-hydroxyflavone derivatives containing 2 to 4 fluorine atoms have been synthesized. Using fluorine derivatives of 3-hydroxyflavone, radiation hard PSs, with a light output half attenuation dose more than 20 Mrad, were obtained. Product Description popup.authors Yelyseev Dmуtro A.
