Abstract

 

Neodymium (Nd³⁺) doped yttrium oxide (Y₂O₃) nanophosphors have emerged as promising materials for various luminescence-based applications, particularly in radiation dosimetry, photonics, and optoelectronic devices. The thermoluminescence (TL) properties of these nanophosphors are of particular interest due to their ability to store and release energy upon thermal stimulation after prior exposure to ionizing radiation. This study provides an in-depth examination of the TL behavior of Y₂O₃:Nd³⁺ nanophosphors, focusing on key parameters such as glow curve characteristics, trap depth energies, frequency factors, and kinetic orders. The glow curves indicates the presence of various trapping levels introduced by Nd³⁺ doping. Using peak shape and deconvolution methods, detailed kinetic parameters are extracted to reveal the underlying recombination processes. The study also compares the TL performance of Nd³⁺-doped Y₂O₃ with that of other rare-earth doped analogs such as Eu³⁺ and Tb³⁺ to establish the unique advantages of neodymium in enhancing trap depth and luminescence efficiency. Potential applications in low-dose radiation detection, UV dosimetry, and persistent luminescence are discussed in the context of the observed TL characteristics. This review aims to provide a consolidated understanding of the structure-property relationships in Y₂O₃:Nd³⁺ nanophosphors and to guide future developments in designing tailored materials for advanced TL-based applications
