Thermoluminescence Glow Curve Analysis with Variable Concentration of Erbium‐Doped Y2O3 Phosphor

Abstract A series of Y 2 O 3 :Er 3+ phosphors have been synthesized via combustion synthesis method using urea as a fuel. The prepared samples are characterized by X‐ray diffractometer (XRD) and Fourier transforms infrared spectroscopy (FTIR) techniques. TL glow curves are recorded for Y 2 O 3 :Er 3+ doped phosphors to study dose dependence, UV response, and heating rate effect. The trapping parameters (μ, E, s) are calculated from Chen's glow peak shape method. TL glow curve is fitted in computerized glow curve deconvolution (CGCD) techniques and are discussed in detail for their possible usage in dosimetry applications.
