Abstract
The invention relates to an optical information recording medium and methods and devices to record and read information thereto and thereof. The optical information recording medium comprises luminescent nano-elements. The nano-element species differ in at least one luminescence wavelength. Therefore, a specific luminescence signal is obtained in accordance with the nano-element species irradited by a reading light beam. Methods and devices to record and read information by using such optical information recording media are also described.
