Abstract Room temperature phosphorescence (RTP) materials are of significant attentions due to their unique optical properties and potential applications in anti‐counterfeiting information security. However, single spatial resolution decryption methods fail meet high‐level security demands. A novel dual‐mode encryption strategy based on self‐trapped exciton (STE) fluorescence is proposed. By introducing ns 2 metal ions into the zero‐dimensional organic–inorganic hybrid halide (Ph 3 S) SnCl 6 , energy transfer pathways from S 1 T n levels STEs constructed, enabling precise control performance. This material exhibited STE fluorescence‐phosphorescence with different afterglow time, which can be utilized develop high‐performance time‐resolved cryptographic systems. Femtosecond transient absorption experiments indicated that rate significantly affected characteristics long materials. The this systems demonstrated, enhancing through multi‐level providing a new avenue for advanced
