Preparation methods of thermoluminescent materials for dosimetric applications: An overview

Preliminary Studies of Thermoluminescence Dosimeter (TLD) CaSO4:Dy Synthesis

“…The TLD CaSO 4 :Dy from the experiment and the TLD BARC have a simple glow curve, but the TLD-900 has a complex glow curve. According to Azorin [4], a good TL material usually has a relatively simple glow curve and has its main peak at about 200 °C. The TLD CaSO 4 :Dy from the experiment has a simple glow curve and all the electrons in the trap were read out.…”

“…One of the fabrication methods is co-precipitation. This method has the advantage of involving a simple and rapid preparation process, it is easy to control the particle size and composition, and it offers several possibilities to modify the particle surface state and overall homogeneity [4,5].…”

Thermoluminescence study of aluminium oxide doped germanium prepared by combustion synthesis method

“…This is due to aluminium oxide (α-Al2O3) shows an effective number close to that of bone (Zeff = 11.28), it becomes a better choice to be used in medical and environmental dosimetry (Bos, 2001). The TL properties of Al2O3 samples of different dopants materials which can enhance TL properties have been studied by several researches for nearly 50 years [1,2] The materials were generally synthesized by sol-gel method [3], ion beam implantation [4], solvent evaporation [5] and combustion synthesis (CS) [6,7,8]. Among this method, combustion synthesis (CS) is an effective and low-cost method for production of various industrially useful materials [9,10].…”

Síntesis y Caracterización de LiF Dopado con Europio para Dosimetría Termoluminiscente por Método de Precipitación

“…Para que un material termoluminiscente pueda ser utilizado en dosimetría se requiere que éste posea ciertas características: una curva de brillo simple con un pico principal cerca de 200°C, alta sensibilidad y estabilidad y resistencia a los factores ambientales [2]. Actualmente se están llevando acabo numerosos estudios para el desarrollo y caracterización de nuevos materiales termoluminiscentes para aplicaciones de dosimetría de radiaciones ionizantes.…”

“…Las propiedades ópticas del LiF pueden ser modificadas utilizando diferentes dopantes como tierras raras, por ello en las últimas décadas ha crecido el interés por estudiar el efecto de diferentes dopantes y distintos métodos de síntesis [2,3]. Entre las tierras raras, los iones de europio (Eu 3+ ) han atraído especial interés debido a sus propiedades ópticas [7,8]; sin embargo aunque las propiedades del LiF han sido extensamente estudiadas [3,4,5], pocos trabajos se han reportado sobre el LiF dopado con Eu.…”
