Nanooptics TRIZ Cases

Direct synthesis of ligand-coated AgInTe2 quantum dots enables biocompatible near-infrared fluorescence with high yield and narrow emission width.

A stacked silicon and quantum dot photodiode uses an optical filter to split visible and infrared light for lower-cost multispectral detection.

Pixel-level nanowire optical filters replace bulky multispectral optics, enabling compact, low-power spectral imaging with accurate material detection.

Rare-earth photoluminescent nanoparticles boost capillary test sensitivity while keeping rapid, simple readout for in vitro detection.

A silane-based fixing layer chemically anchors quantum dots during QLED patterning to prevent detachment and keep patterns regular.

Flash-injection cation exchange forms copper-doped PbS nanocrystals with narrower 1330-1550 nm emission and higher radiative rates.

Nanoscale metal particle hotspots and dielectric contact stabilize heterogeneous layers, boosting microstructure bonding strength and energy efficiency.

An InP core with a ZnSe shell and surface ligands helps quantum dots resist luminance loss under high-brightness display operation.

A spaced metal nanofilm boosts carrier balance and plasmonic light coupling in light-emitting elements while limiting quenching and extending service life.

Opposite-side ligands on a quantum dot tune hole and electron transport, improving injection balance and luminous efficiency in light emitters.

A ZnO-PAH core-shell quantum dot uses Type II energy alignment to confine electron transitions in PAH and suppress non-blue emission.
