Dependence of thermoluminescence glow curve of alumina ceramic radiation detectors with the heating rate

Brazilian Journal of Radiation Sciences, 2021
Anion defective single crystal detectors α-Al2O3 grown by the Czochralski method are widely used for personal and area monitoring. A methodology for the production of polycrystalline ceramic detectors α-Al2O3 based on the sol-gel method was developed in ...

Thermoluminescence and optical absorption studies of highly pure KCl crystals [PDF]

, 1971
The existence of colored specimens of normally colorless minerals has been known for much longer than a century and has created excitement among mineralogists, physicists and chemists. Since early 1800, researchers have studied this coloration phenomenon

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
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 ...

Estimation of the time of exposure from the differential fading of luminescent detectors [PDF]

EPJ Web of Conferences
Containment and surveillance measures for unattended or remotely monitored items and areas serve to detect, timestamp, and thereby deter the illicit movement and trafficking of radioactive material in the interval between two successive inspections. This

Unusual Thermally Induced Blueshift and Emission Amplification of Mn2+ Ions Enable Filter‐Free Luminescent Thermal Imaging

Advanced Science, EarlyView.
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.
