Light-sensitive polymer materials with embedded chromone dyes are promising candidates for multi-layer fluorescent disks for archival storage of information. The recording is based on two-photon-induced phototransformation and the signal readout is due to single-photon-induced luminescence. The stability of fluorescent chromone compounds upon readout irradiation was studied and local quantum yields of luminescence were measured using the LSM710 confocal laser scanning microscope (Carl Zeiss) in order to estimate the material efficiency.
