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

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.
