Irradiation temperature response on Thermoluminescence glow curves of LiB4O7: Cu, In and MgB4O7: Dy, Na artificial luminescence materials

Abstract

Both Li₂B₄O₇: Cu, In and MgB₄O₇: Dy, Na are well established thermoluminescence (TL) materials. Until now, many scientists focused on these materials by studying many properties of these luminescence materials but still the irradiation temperature response of either material hasn’t been studied.  Irradiation temperature response could be a crucial parameter in many applications, such as dating, reactor core dosimetry, space research, temperature exposure monitoring, high dose dosimetry, and in space, polar and hot desert region TL studies.  Moreover, Irradiation temperature response enables us to better understand the TL phenomenon.  In this study both the irradiation temperature and post irradiation annealing responses of the aforementioned artificial luminescence materials were investigated in detail.

LiB4O7:Cu,In ve MgB4O7:Dy,Na yapay lüminesans malzemelerinde ışınlama sıcaklığının Termolüminesans ışımaya etkisi

Abstract

Termolüminesans (TL) dozimetreler arasında LiB₄O₇: Cu, In ve MgB₄O₇: Dy, Na malzemeler; doku eşdeğerliği, yüksek hassasiyeti, doğrusal doz cevabı gibi özellikleri sayesinde son birkaç yıldır bilim insanlarının ilgisini çekmektedir.  Bugüne dek malzemelerin bazı özellikleri incelenmiş olmasına rağmen henüz ışınlama sıcaklık değişimine verdikleri cevaplar detaylı olarak incelenmemiştir.  Oysa ışınlama sıcaklığı tarihlendirmede, radyasyon doz ölçümlerinde, uzay, kutuplar, çöller gibi uç ortamlarda yapılacak dozimetri çalışmalarında büyük bir öneme sahiptir.  Ayrıca ışınlama sıcaklık değişimi malzemelerdeki TL süreçlerinin anlaşılmasına da imkân sağlama potansiyeli vardır. Bu çalışmada LBO ve MBO’da gözlenen TL ışıma eğrilerinin ışınlama sıcaklığına ve oda sıcaklığında ışınlama sonrası yüksek sıcaklıklarda tavlanmaya verdikleri cevaplar detaylı olarak incelenmiştir.
