摘要

A fluorescent method comprising changing charge amount in an organic dye thin film by a voltage applied between a pair of electrodes, and increasing and decreasing efficiency of fluorescence generated by exciting the organic dye thin film with a light source depending on the change of the charge amount is disclosed. A fluorescent device comprising an organic dye thin film, a pair of electrodes disposed to apply pressure to the organic dye thin film and a light source generating fluorescence by exciting the organic dye thin film, wherein efficiency of the fluorescence is increased and decreased depending on the change of the charge amount in the organic dye thin film by voltage applied between the electrodes is also disclosed. A fluorescent recording method comprising accumulating charges in an organic dye thin film by a voltage applied between a pair of electrodes, changing efficiency of fluorescence of the organic dye thin film depending on the accumulation of charges and recording is also disclosed.
