Formation and evolution of oxygen vacancies in ZnO white paint during proton exposure

The formation and evolution of oxygen vacancies in ZnO white paint during <200 keV protons exposure was investigated using photoluminescence spectroscopy. After irradiation, the shape of photoluminescence spectra changes little, but the peak height decreases. With increasing fluence, the amount of doubly ionized oxygen vacancies decreases, while that for the singly ionized oxygen vacancies increases. The former can trap electrons in the conduction bands to become the singly ionized oxygen vacancies, leading to that the latter gradually becoming the major defects induced by irradiation. The increase in content of singly ionized oxygen vacancies due to the irradiation can also promote an increase in the amount of absorbed oxygen in the paint, enhancing the quenching effect of photoluminescence and thus decreasing the photoluminescence peak.     

Radiation induced defects in BaBPO5:Ce and their role in thermally stimulated luminescence reactions: EPR and TSL investigations

Defect centers induced by gamma irradiation in Ce doped BaBPO₅ were investigated using EPR spectroscopy. From EPR studies, three phosphorous centered radicals were characterized on the basis of observed ³¹P hyperfine splitting and g values as , and radicals. In addition to this, two types of boron oxygen hole centers (BOHC) and O⁻ were also formed at room temperature. An intense broad signal in sample annealed in argon (g_⊥ = 1.9258 and g_‖ = 1.8839) was assigned to Ce³⁺ ions associated with the electron trapped at anion vacancy or nearby lattice defect. TSL studies showed two glow peaks, a relatively weaker one at 425 K and an intense one at 575 K. Spectral studies of the TSL glow peaks have shown that Ce³⁺ ion acts as emission center. From the temperature dependence of the EPR spectra of gamma irradiated samples, the glow peaks at 425 K and 575 K were attributed to thermal destruction of /O⁻ and BOHC, respectively, by trapping of electrons from elsewhere. The energy released in electron hole recombination process is used for the excitation of Ce³⁺ ions resulting in these glow peaks at 425 K and 575 K. The spectral studies of the TSL glow peaks have shown emission at 330 nm indicating Ce³⁺ acts as the luminescent centre. The trap depth and the frequency factor for the 425 K and 575 K peaks were determined using different heating rates method.

Synthesis of KNaSO4:Tb and MgSO4:Dy phosphors for lyoluminescence dosimetry

KNaSO₄:Tb³⁺ phosphors were synthesized by melt technique with different concentration of Tb³⁺ ions and MgSO₄:Dy³⁺ phosphor is prepared by solid state diffusion method. Lyoluminescence and photoluminescence characterization of KNaSO₄:Tb and MgSO₄:Dy³⁺ phosphors are reported in this paper. Only one sharp peak is observed in the lyoluminescence (LL) glow curve and KNaSO₄:Tb(0.05 mol%) phosphor shows maximum efficiency. The LL intensity increases linearly with gamma ray dose. LL emission occurs in the blue and yellow region of the spectrum. Photoluminescence (PL) characterization of KNaSO₄:Tb(0.05 mol%) phosphor shows PL emission at 486 and 546 nm. These PL emissions from KNaSO₄:Tb³⁺ are due to ⁵D₄ → ⁷F₆ and ⁵D₄ → ⁷F₅ transitions of Tb³⁺ ion respectively. Lyoluminescence of MgSO₄:Dy³⁺ phosphor shows the high sensitivity to γ-ray exposure and LL emission observed at 486 and 572 nm in the blue and yellow emission of the spectrum is due to Dy³⁺ ion. Experimental results obtained in the present investigation show that KNaSO₄:Tb³⁺ and MgSO₄:Dy³⁺ phosphors are suitable as a lyoluminescence dosimetry phosphor for ionizing radiations.
