Copper iodide based highly luminescent phosphor can produce internal quantum yield of up to 98% when excited with 365 nm light
Invention Summary:
The global market for light-emitting diodes (LEDs) is projected to account for up to 80% of light sources by 2030. However, the commercial phosphor used during their fabrication is made from rare-earth elements (REEs); hence contributing to mining-related environmental hazards.
Rutgers researchers have developed highly efficient REE-free phosphors that can offer comparable performance to commercial phosphors with their high internal quantum yield (IQY). These phosphors have high solution processability and enhanced thermal and photostability. The fabrication methods can be generalized and repurposed for similar applications.
There are three technologies from Rutgers Professor Jing Li related to REE-free phosphors, including:
.
Market Applications:
- Residential/ Commercial lighting
- Horticulture lighting
- Photovoltaics
Advantages:
- No use of REEs
- High luminescence and IQY
- High solution processability
- Low correlate color temperature
