Luminescence study of LiMgBO :Dy for γ-ray and carbon ion beam exposure.

LiMgBO :Dy , a low Z material was prepared using the solution combustion method and its luminescence properties were studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), thermoluminescence (TL), photoluminescence (PL), Fourier transform infrared spectroscopy, and electron paramagnetic resonance (EPR) techniques. Reitvield refinement was also performed for the structural studies. The PL emission spectra for LiMgBO :Dy consisted of two peaks at 478 due to the F → H magnetic dipole transition and at 572 nm due to the hypersensitive F → H electric dipole transition of Dy , respectively.

Green-light emission through energy transfer from Ce to Tb ions in the Li SO -Al (SO ) system.

An energy transfer process from Ce to Tb ions was successfully achieved in a Li SO -Al (SO ) mixed-sulphate system. A wet-chemical synthesis was employed to prepare the Li SO -Al (SO ) system by doping Ce and Tb ions individually as well as collectively. The phases were identified using X-ray diffraction studies.

Comparison of thermoluminescence characteristics in γ-ray and C(5+) ion beam-irradiated LiCaAlF6 :Ce phosphor.

We compare the thermoluminescence (TL) behavior of Ce(3+) ion-activated LiCaAlF6 exposed to γ-rays and a carbon ion beam. The reported phosphor is synthesized using an in-house precipitation method with varying concentrations of activator ion and is characterized by X-ray diffraction (XRD) and TL. Rietveld refinement is performed to study the structural statistics.
