The fast emission around 185 nm with a decay time of several nanoseconds was due to the allowed 5d-4f transition of the Nd<sup>3+</sup> ion. The high temperature phase BaLu<sub>2</sub>F<sub>8</sub> orthorhombic crystals have been prepared by micro-pulling-down method. Unfortunately, no 5d-4f emission (neither from Nd<sup>3+</sup> nor from Tm<sup>3+</sup>) was observed in the crystals under excitation by ionizing radiation at all. This was explained by preferential energy transfer from the host to the lattice defect states. Further improvement of the scintillation efficiency by facilitating the energy transfer from the host matrix to the Nd<sup>3+</sup> luminescence center by Tm<sup>3+</sup>-codoping was attempted. The energy transfer from the Tm<sup>3+</sup> ions to the Nd<sup>3+</sup> ones has been proved, however, no improvement of the overall scintillation efficiency was observed.</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; crystal growth from melt; defect states; neodymium; photoluminescence; scintillation; thulium; 5d-4f transition; BaLu<sub>2</sub>F<sub>8</sub>:Nd,Tm; codoping; decay time; energy transfer; high temperature phase orthorhombic crystals; ionizing radiation; lattice defect states; luminescence center; luminescence properties; micropulling-down method; monoclinic single crystals; orthorhombic single crystals; rare-earth-doped orthorhombic vacuum-ultraviolet scintillator crystals; scintillation efficiency; scintillation properties; Crystals; Energy exchange; Erbium; Ions; Photoluminescence; Fluorides; rare-earth doping; scintillator; x-ray and gamma-ray detection;</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.2013.2280505</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'>6636092</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=57373' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=57373</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
