Dynamic 3D-Luminescence: Simultaneous combined X-Ray, Temperature and Cryogenic Control
Aim
The objective of this setup is to perform 3D-Luminescence Mapping (Intensity vs. Wavelength vs. Temperature/Time). By observing the emission spectrum change in real-time during irradiation or heating from -50°C to 710°C, researchers can:
Fingerprint Minerals: Identify characteristic luminescence centers.
Study Kinetic Parameters: Observe trap filling and emptying in real-time from -50°C up to 710°C.
Optimize Dating Protocols: Select the best filters based on spectral sensitivity.
Improve development of advanced scintillators and persistent phosphors.
Trap Distribution: Analyzing trap depth Emission Site Identification: Distinguishing do-pant sites via 3D spectral resolution.
Scintillator Optimization: Measuring charging kinetics and afterglow via Radio-Luminescence (RL).

Solution
The Integrated Multi-Tool Setup
lexsygresearch is the only system capable of housing all these components simultaneously without cross-interference.
X-Ray Irradiation: Integrated miniature X-ray tube for Radio-Luminescence (RL).
High-Range Heater: Precise linear heating up to 710°C.
Peltier Cooling: Cryogenic capability down to -50°C.
Spectroscopic Detection: CCD/EMCCD for full-spectrum continuous acquisition.
Application example
Lu2Si2O7:Ce (LPS) Scintillators
Research at Clemson University utilized the lexsygresearch to solve timing resolution issues in silicate scintillators.
The lexsygresearch revealed multiple TL peaks across the full temperature range, allowing the team to model kinetics and optimize co-doping strategies to suppress afterglow.
