摘要

In this study, a microwave-assisted combustion technique was used to create gadolinium aluminate phosphors (GAP), gadolinium aluminate phosphors doped with terbium (GAP: Tb), and gadolinium aluminate phosphors doped with boron (GAP: Tb, B). The structural properties of the phosphors were investigated using X-ray diffraction (XRD) analysis. The photoluminescence (PL) emission and excitation spectra of GAP: Tb and GAP: Tb, B phosphors were studied. In this study, the luminescence properties of Tb-doped GAP materials were examined by considering the contributions of the boron ions. As a result, it was determined that the photoluminescence intensity increased with boron doping in GAP: Tb. The thermoluminescence (TL) properties of the phosphors were also examined. The impact of Tb (terbium) and B (boron) doping on the thermoluminescence features of GAP materials was investigated by analyzing thermoluminescence glow curves after irradiation with 365, 302, and 254 nm ultraviolet (UV) radiation.
