- A dysprosium-activated potassium calcium silicate phosphor (KCS:Dy) was successfully synthesized using a solid-state method, displaying a cubic structure as confirmed by X-ray diffraction.
- Techniques like scanning electron microscopy and energy-dispersive X-ray spectroscopy were employed to analyze the surface and elemental composition, while Fourier transform infrared spectroscopy assessed its chemical structure and vibrational modes.
- The phosphor demonstrated strong yellow emission under UV light, excellent thermal stability, and a suitable optical bandgap, making it a promising candidate for use in UV-based white light-emitting diodes.
Article Synopsis
- The study synthesized samarium ion (Sm)-doped alkali zinc alumino borosilicate (AZABS) glass using a quick melt quench technique and conducted multiple spectroscopic studies on it.
- Under 402 nm excitation, the glass emitted three sharp photoluminescence bands with the highest intensity observed at a 0.25 mol% Sm concentration, which also indicated dipole-dipole interactions among ions.
- The glass exhibited a direct bandgap of 2.88 eV, good thermal stability with an activation energy of 0.19 eV, and varying lifetimes for Sm concentrations, suggesting potential applications in white-light emitting diodes and solid-state lighting.
Chronic myelogenous leukemia (CML) is a myeloproliferative disorder occurs in the pluripotent hematopoietic stem cell. Currently, first-generation tyrosine kinase inhibitor (TKI) imatinib is the mainstay for the treatment of CML. Second generation TKI's like ponatinib, dasatinib, nilotinib, and bafetinib were treated against resistant CML.
