Provided is a compound semiconductor deposition method of adjusting the luminous wavelength of a compound semiconductor of a ternary or higher system in a nanometer order in depositing the compound semiconductor on a substrate. In the compound semiconductor deposition method of depositing a compound semiconductor of a ternary or higher system on a substrate, propagation light of a smaller energy than a desired ideal excitation energy for the compound semiconductor is irradiated onto the substratewhile depositing the compound semiconductor on the substrate, near-field light is generated based on the irradiated propagation light from fine particles of the compound semiconductor deposited on the substrate, new vibrational levels for the compound semiconductor are formed in multiple stages based on the generated near-field light, and a component in the compound semiconductor corresponding to the excitation energy is excited with the propagation light through a vibrational level, among the new vibrational levels, which has an excitation energy equal to or smaller than the energy of the propagation light is excited to desorb the component.
