[Display omitted] •Polymer layers with photoinduced fluorescence were prepared and studied.•Layers with diarylethenes and fluorophors may be used in working optical memory.•Layers based on chromones are intended for archival optical memory.•Developed layers provide making multilayer optical disks (ODs) of new generation.•ODs have a super high capacity and nondestructive fluorescent readout. The results of the development of optical fluorescent solid film materials for applications as recording media for two-photon three-dimension bitwise optical memory with nondestructive fluorescent readout are presented. It was shown that photochromic diarylethenes in combination with organic fluorophore phenalenone or inorganic quantum dots CdSe/ZnS provide preparation of multilayer optical disks for working optical memory. Polymer layers based on irreversible light – sensitive chromones are acceptable for making optical disks of the archival type.
