Method for producing a fine particle array structure, method of producing the light reflecting medium, and apparatus used in these production methods

摘要

PPROBLEM TO BE SOLVED: To provide a production method for particulate arrangement structure with little defect, a production method for optical media with little defect, and production apparatuses used for production thereof. PSOLUTION: The production apparatus in the figure for the particulate arrangement structure is provided with a device 5 partially speeding up vaporization rate of a dispersion medium. In this apparatus, after a particulate dispersion liquid 2 is applied on a substrate 1, the dispersion medium is quickly vaporized from the dispersion liquid 2 positioned facing the device 5, speeding up the vaporization rate of the dispersion medium, and remaining particulates are deposited on the substrate 1 to self-organizingly form a particulate assembly 3. By moving the device 5 to the dispersion liquid 2 side in conformity to the growth of the particulate assembly 3, a growth end 4 of the assembly 3 is moved to the dispersion liquid 2 side to control the growth direction of the assembly 3.
