Single crystals of BaBrI and CsBa<sub>2</sub>I<sub>5</sub> were grown from the melt by the vertical Bridgman technique. Crystals were doped with 8% and 4% Eu<sup>2+</sup> for BaBrI and CsBa<sub>2</sub>I<sub>5</sub> , respectively. These crystals have higher optical quality and present improved scintillation performance compared to the previously reported values. An estimated light yield of 97,000±5,000 and 102,000±6,000 photons per MeV (ph/MeV) of absorbed gamma-ray energy is now measured for BaBrI:8%Eu<sup>2+</sup> and CsBa<sub>2</sub>I<sub>5</sub>:4%Eu<sup>2+</sup> , respectively. A better energy resolution has also been observed. BaBrI energy resolution for the 662 keV full absorption peak (FWHM over peak position) decreased to 3.4±0.2% and CsBa<sub>2</sub>I<sub>5</sub>:4%Eu<sup>2+</sup> energy resolution decreased to 2.55±0.2% . Additional measurements show both scintillators with an excellent light yield proportionality. Finally, based on optical and x-ray excited emission spectra and decay curves, energy transfer mechanisms in BaBrI and CsBa<sub>2</sub>I<sub>5</sub> scintillators are briefly discussed.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>barium compounds; bromine compounds; caesium compounds; europium; gamma-ray detection; scintillation counters; BaBrI:Eu; CsBa<sub>2</sub>I<sub>5</sub>:Eu; gamma-ray energy; optical property; scintillation performance; scintillation property; vertical Bridgman technique; Crystals; Energy measurement; Energy resolution; Optical variables measurement; Stimulated emission; Temperature measurement; Wavelength measurement; Energy resolution; europium; halides; proportionality; scintillator;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Nuclear Science, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>0018-9499</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TNS.2011.2166999</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6060932</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1362065' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1362065</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
