Information multimode encryption and decryption method based on europium nano aggregate fluorescent non-woven fabric

The invention discloses an information multimode encryption and decryption method based on europium nano aggregate fluorescent non-woven fabric. The method comprises the following steps: step 1, preparing europium nano aggregate-containing fluorescent non-woven nano fabric; 2, multimode encryption of light quantum information: printing/writing a plurality of quenching inks on the polymer-based nano non-woven fabric prepared in the step 1 in a printing or/and writing manner, so as to encrypt and write the information into the nano non-woven fabric; and step 3, multimode decryption of the light quantum information: setting decryption codes in one-to-one correspondence with the decryption steps and the decryption agents, performing operation according to the decryption steps indicated by the decryption codes, and processing the nano non-woven fabric obtained in the step 2 in a plurality of decryption steps by adopting the decryption agents indicated by the decryption codes to obtain the multi-mode decryption of
