Abstract

The invention provides a white light photonic crystal with a nanometer micro lens array and a preparation method thereof. The white light photonic crystal with the nanometer micro lens array comprises a photoetching mask plate with patterns, and is made of quartz and provided with a chromium metal layer; a negative photoresist is coated on the photoetching mask plate and distributed with a ferro-nickel alloy electroplating liquid, thus forming a metal shielding layer with a nanometer micro lens; and distributing red, green and blue transparent fluorescent gel forming red, green and blue nanometer micro lens after being baked in patterns of the metal shielding layer and printing the red, green and blue transparent fluorescent gel on multiple quantum wells of the metal shielding layer.

Description

technical field [0001] The invention relates to optical crystal technology, more specifically, to a white light photonic crystal with a nanometer microlens array and a preparation method thereof. Background technique [0002] Photonic crystals are photonic bandgap materials. From the perspective of material structure, photonic crystals are artificially designed and manufactured crystals with periodic dielectric structures on the optical scale. The structure of photonic crystals is just like the periodic appearance of ions in the crystal lattice nodes of semiconductor materials. Photonic crystals are materials with low refractive index (such as artificially caused air holes) that periodically appear in certain positions of high refractive index materials. Materials with high and low refractive indices are arranged alternately to form a periodic structure, which can produce a photonic crystal band gap. However, the distances between the periodically arranged low-refractive in...
