Abstract:In this work, 9,10-diphenylanthracene
(DPA) crystals in centimeter
size were grown by melt as well as solution methods. The optical properties
of both crystals were investigated using X-ray stimulated luminescence
spectra. The strongest emission wavelengths are around 454 and 469
nm for DPA-Melt and DPA-Solution, respectively, a longer wavelength
than that of stilbene. The scintillation properties were measured
with a digitizer and pulse shape discrimination method. The crystal
by melt method got the largest l… Show more
“…6 In contrast to trans-stilbene, the light yield of DPA crystals synthesized using melt growth is reportedly larger than that of DPA crystals synthesized using solution growth. 7 Furthermore, 1,4-bis(2-methylstyryl) benzene (bis-MSB) and carbazole crystals have been developed for the detection of a-rays and neutrons. 8,9 Bis-MSB crystals exhibit a light yield 1.4 times larger than that exhibited by trans-stilbene crystals (12 000 vs. 8500 photons/5.5 MeV a-ray).…”

“…12 The PSD FOM of bibenzyl crystals with stilbene is more favorable than that of diphenylacetylene crystals with stilbene. 13 Although the development of crystal growth techniques to optimize the size and scintillation properties of established compounds has been considerably emphasized, 4,7,13 that of novel organic crystal scintillators has received relatively limited attention. Organic crystal scintillators are typically developed using dispersed organic phosphors in conventional plastic and liquid scintillators to improve their performance; therefore, the discovery of organic phosphors with favorable scintillation properties is of urgent importance.…”
