✓Characterize local luminescence properties of phosphor materials
✓Interpret CL data to assess phosphor stability and performance
Protocol
An excellent chemical and luminescence stabilities of (oxy)nitride phosphors present it as an promising alternative to currently used sulfide and oxide phosphors. In this paper, we present the way to investigate its local luminescence properties using low-energy cathodoluminescence (CL).
Difficulty
advanced
Total time
~4–6 hours per sample set (including preparation and imaging)
Steps
1
Prepare (oxy)nitride phosphor samples
Process and mount (oxy)nitride phosphor materials on suitable substrates for subsequent cathodoluminescence imaging. Ensure samples are clean and properly positioned for analysis.
