Our proprietary nanoparticle technology is built on the inter-particle energy transfer (IFRET) principle.
We combine two purpose-built nanomaterials:
- Blue-absorbing sensitizer (e.g., YAG:Ce)
- Eu³⁺-based emitter
By engineering these two materials at the nanoscale and positioning them with precision, energy absorbed by the sensitizer is transferred directly to the emitter, which then emits the desired color.
While energy transfer between ions is not new, conventional methods embed both ions in a single host material. This often leads to quenching, where the light is lost due to uncontrolled interactions between ions, making the blue absorption of Eu³⁺ particularly problematic.
Our breakthrough lies in decoupling the materials. By choosing separate hosts for both the sensitizer and emitter, and by precisely controlling the distance between them, we enable efficient energy transfer while preventing performance losses.
This design flexibility means we can fine-tune each component for optimal absorption, emission, and stability, without any compromise.
