Abstract

Using temporal dimension in optical multiplexing is a promising method to increase the security of data encryption. However, adjusting the fluorescence lifetime of light-emitting material often results in inevitable changes in their fluorescence spectra, which is unfavorable for confidential information protection. Here, we report the preparation of various perovskite quantum dot/polymer nanospheres (PQD/polymer) with tunable and long fluorescence lifetimes but identical fluorescence spectra, which are ideal multidimensional data encryption materials. This new data encryption strategy utilizes the water sensitivity of perovskite and achieves spatial dimension encryption of information using different water stabilities between uncoated perovskite quantum dots and PQD/polymer. The fluorescence lifetime of PQD/polymer is used as the coding element to achieve temporal dimension data encryption, and the data are decrypted by fluorescence lifetime imaging microscopy and time-gated luminescence imaging techniques. This study shows the potential of PQD/polymer as a new class of materials for advanced data encryption.
