- Teams developed a new forensic approach revealing gunshot residue using perovskite-based photoluminescence.
- Discharging firearms deposits lead residue on surfaces, unlike current lab-dependent analysis methods.
- The process converts lead particles into light-emitting semiconductors visible as green patterns with a reagent.
- A forensic expert states finding residue at the scene is a "major advantage," says Bente van Kralingen.
- The method remained effective after washing and detects traces two meters away, aiding incident reconstruction.
