Thermoluminescence of zircon: a kinetic model [PDF]

Journal of Physics: Condensed Matter, 2003
The mineral zircon, ZrSiO4, belongs to a class of promising materials for geochronometry by means of thermoluminescence (TL) dating. The development of a reliable and reproducible method for TL dating with zircon requires detailed knowledge of the processes taking place during exposure to ionizing radiation, long-term storage, annealing at moderate ...

Unusual Thermally Induced Blueshift and Emission Amplification of Mn²⁺ Ions Enable Filter-Free Luminescent Thermal Imaging. [PDF]

Adv Sci (Weinh)
ABSTRACT The shift from point‐based thermal sensing to filter‐free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spectral regions matching the sensitivity profiles of the red, green and blue (RGB) channels of a digital camera.

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare-Earth Long Persistent Luminescence. [PDF]

Adv Sci (Weinh)
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...
