Luminescent Compositions TRIZ Cases
- Protective Nanoparticle Structure for Stable Optoelectronic Emission
Non-chromophoric nanoparticles intercept moisture and other degrading species to preserve semiconductor emission and extend optoelectronic lifetime.
- Quantum Dot Photodetector Filtration for Lower Dark Current
Filtering the quantum dot dispersion before film formation suppresses soft aggregates, improving film uniformity, dark current, and yield.
- Silicon UV Photodetector Structure With Perovskite Down-Conversion
A halide-perovskite down-conversion layer turns UV light into visible light, helping silicon photodetectors avoid surface losses and detect UV more accurately.
- Nitridophosphate Red Phosphor Composition for White LED Color Rendering
A Eu-doped nitridophosphate phosphor converts near-UV or blue light to red, improving white LED efficacy and Ra8 color rendering.
- InSb/InP Core-Shell Quantum Dots for Low-Defect SWIR Detection
An InP shell passivates InSb quantum dots to suppress Sb oxidation and surface defects, enabling efficient, fast SWIR photodetectors.
- Nitride Phosphor Sintered Body for Stable Luminous Flux
Using a nitride binder instead of fluoride prevents calcination reactions, preserving luminous flux and color-controlled emission in light-emitting devices.
- Spinel-Bonded Phosphor Plate for Higher Light Extraction
Replacing SiO2 glass with a spinel sintered body cuts light scattering in α-sialon phosphor plates and boosts orange LED brightness.
- Fluorine-Shelled Quantum Dots for Stable High-Yield Emission
HF surface treatment removes core defects before shell growth, improving quantum yield retention, chemical stability, and color reproducibility.
- Phosphor Composition for Stable LED Color Conversion
A tailored phosphor composition stabilizes LED color output despite chip wavelength shifts while improving conversion efficiency and color rendering.
