摘　　要：High resolution and full-color light-emitting diodes require precise and efficient patterning of light-emitting structures containing quantum dots or nanocrystals.We report light-induced inverted patterning of nanocrystals in glasses for micro-light-emitting diodes.Ultrafast laser pulse induces structural destruction and amorphization of nanocrystals in glasses,forming inverted luminescent patterns.High-throughput patterning of micrometer-scale,thermally stable,and highly photoluminescent structures in nanocrystals embedded glass is realized.This patterning method provides a novel way to fabricate high-performance and ultrahigh-resolution color conversion layers for micrometer-scale light-emitting diodes.
