Ultrafast core-to-core luminescence in BaF2 - LaF3 single crystals

Scientific Reports
This study investigates the mechanisms underlying the ultrafast cross-luminescence observed in BaF2 crystals doped with LaF3. We identified an ultrafast luminescent component with a decay time of approximately 150 ps, which emerges under excitation ...

Study on fracture parameter calibration and failure characteristics of rock with hole and crack

Deep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...
