Method for fabricating an electroluminescence device

A method for fabricating an electroluminescence device, comprising the steps of:

• patterning a hole-injecting anode on a substrate and forming a polymer hole transport layer thereon;
• coating a nanocrystal dispersion on the polymer hole transport layer to form a nanocrystal light-emitting layer;
• forming an organic electron transport layer on the nanocrystal light-emitting layer;
• and
• forming an electron-injecting cathode on the organic electron transport layer,
• wherein the nanocrystal light-emitting layer is formed by dispersing nanocrystals surface-bound by a photosensitive compound in a solvent which does not damage the polymer hole transport layer to obtain a nanocrystal dispersion, and coating the nanocrystal dispersion on the polymer hole transport layer;
• or dispersing nanocrystals surface-bound by a material containing no photosensitive functional group and a photosensitive compound in a solvent which does not damage the polymer hole transport layer to obtain a nanocrystal dispersion, and coating the nanocrystal dispersion on the polymer hole transport layer.
