Abstract

The invention relates to a method for preparing monocrystalline diamond inverse opal by adopting an LB mask plate. A problem to be solved is that an existing diamond inverse opal structure can only prepare polycrystals, so that comprehensive performances of the polycrystals in dynamics, optics and thermology are reduced. The method comprises a first step of diamond wafer pretreatment; a second step of SiO2 microsphere pretreatment; a third step of mask plate deposition; a fourth step of mask plate treatment; a fifth step of single layer inverse opal monocrystalline diamond growth; a sixth step of growth aftertreatment; a seventh step of multi-mask plate deposition and diamond growth; and an eighth step of mask plate removal.

Description

technical field [0001] The invention relates to a preparation method of single crystal diamond inverse opal. Background technique [0002] Photonic crystals are photonic bandgap materials, which are artificial microstructures that are periodically arranged by media with different refractive indices. From the perspective of material structure, photonic crystals are a type of artificial microstructure with periodic dielectric structures on the optical scale. Crystals designed and manufactured. Similar to the modulation of electronic wave functions by semiconductor lattices, photonic bandgap materials can modulate electromagnetic waves with corresponding wavelengths - when electromagnetic waves propagate in photonic bandgap materials, they are modulated due to the existence of Bragg scattering, and the energy of electromagnetic waves forms an energy band structure . There is a band gap between the energy band and the energy band, that is, the photonic band gap. Photons with ...
