Structured Quantum Dot Material with 21 Times Higher Luminous Intensity to Reduce Micro LED Cost

A research team of The Korea Advanced Institute of Science and Technology (KAIST) developed a new light-emitting material which combines quantum dot with a polymer medium filled with popcorn-like air bag. The new material, compared to conventional pure quantum dot films, perform 21 times better luminous intensity and 45% better durability. The study was published online in September on Nano Letters, titles “Order-of-Magnitude, Broadband-Enhanced Light Emission from Quantum Dots Assembled in Multiscale Phase-Separated Block Copolymers.”
