Study and characterization of luminiscent and optical properties of European impurified MgF₂

Currently, personal dosimeters are around the prices between $14.60 and $12.29 per unit according to ARUTEC LATAM, due to this, the opportunity for research in the synthesis of new and low-cost materials has been taken. The luminescent properties of rare earth (Ce, Tb) doped MgF₂ has been studied for its application in scintillators and lasers, and there are already new works where the impurification with rare earths improve its luminescent properties. Through precipitation synthesis, a promising Eu3+ doped MgF₂ material has been developed. The thermoluminescence response is composed by an intense maximum at 235°C and low intense maxima at low temperatures (56,138, 227, 300 y 375°C). This material was characterized by X-ray diffraction (XRD) obtaining a set of three crystalline phases, KNO₃, MgF₂ and KMgF₃ and scanning electron microscopy (Sem) showing a homogeneous structure, in addition photoluminescence studies have been performed to confirm the incorporation of europium ions into the crystal network. The luminescent properties of MgF₂:Eu were analyzed using different concentrations of Eu and a repeatability test of synthesis was also carried out. (author)
