Rare Earth Metal Compounds TRIZ Cases
- Core-Shell Upconverting Microparticles for Weak Near-Infrared Detection
Hexagonal core-shell upconverting microparticles convert weak near-infrared light to visible emission with lower-cost sol-gel production.
- Garnet Oxide Powder Composition for Low-Absorption Transparent Ceramics
Coprecipitated Tb-Y-Al-Sc garnet powder enables transparent ceramics with higher Verdet constant and lower light absorption for Faraday rotators.
- β-Sialon Phosphor Powder Aggregation Control for Brighter White LEDs
Controlling β-sialon phosphor aggregation through a D1/D2 particle-size ratio improves white LED brightness, luminous flux, and dispersibility.
- Rare-Earth Garnet Nanoparticle Synthesis With Stable Sub-10 nm Control
A glycol-alcohol solvent mixture and controlled high-pressure heating produce crystalline garnet nanoparticles with high quantum yield.
- Yb2O3 Sintered Body for Semiconductor Corrosion Resistance
Low-porosity Yb2O3 sintered bodies resist reactive plasma etching, solving adhesion and degradation issues in electrostatic chucks.
- Lanthanide-Doped Perovskite for Rapid Hydrochromic Response
Lanthanide doping in halide perovskites achieves rapid hydrochromic response while eliminating lead toxicity and stabilizing luminescence.
- SiEuAlON Fluorescent Material Light Emission Intensity
SiEuAlON fluorescent material composition enhances light emission intensity by resolving the contradiction between high output and manufacturing complexity.
- Ceramic Composite Eluting Aluminum Oxide for Luminous Flux
Eluting aluminum oxide from a sintered body exposes fluorescent material, reducing reflection and scattering to improve luminous flux.
