High temperature photoluminescence dependence and energy migration of Tb-Incorporated KY(BO) phosphors.

This study investigates the structural and photoluminescence (PL) characteristics of Tb-incorporated KY(BO) (KYBO) phosphors synthesized via a microwave-assisted sol-gel technique. X-ray diffraction (XRD) and Rietveld refinement confirmed the formation of a pure hexagonal phase, with lattice expansion due to Tb³⁺ doping. PL studies revealed strong green emissions centered at 541 nm, attributed to the ⁵D₄ → ⁷F₅ transitions of Tb³⁺ ions, with the highest intensity observed at 5 wt% Tb³⁺.

Beta irradiation-induced thermoluminescence: Glow curve analysis and kinetic parameters in combustion-synthesized undoped CaYO(BO).

This study examines the thermoluminescent (TL) properties of undoped CaYO(BO) phosphor, focusing on how it behaves under a variety of experimental conditions. The IRSL-TL 565 nm was chosen as the appropriate detection filter among various optical detection filter combinations. During the preheating trials conducted at a rate of 2 °C/s, the TL peak exhibited increased intensity, particularly around 200 °C.

Temperature-responsive insights: Investigating Eu and Dy activated yttrium calcium oxyborate phosphors for structure and luminescence.

An investigation into the luminescent behavior of YCOB (Yttrium Calcium Oxyborate) doped with Eu and Dy ions, synthesized via the combustion method, is presented.
