Inorganic　photochromic　(PC)　materials　are　increasingly　considered　as　important　media　for　optical　information　storage　and　multi-level　encryption　anti-counterfeiting.　However,　most　traditional　materials　are　based　on　their　static　properties,　posing　a　serious　security　threat　to　the　stored　information.　To　address　this　issue,　a　strategy　is　proposed　for　kinetics-tunable　PC　(K0.5Na0.5)NbO3　ceramic　that　comprehensively　utilize　the　static　and　dynamic　characteristics　of　matters.　The　prepared　(K0.5Na0.5)0.95Sr0.04Pr0.01NbO3　(SP-y)　ceramics　displayed　two　different　excellent　optical　properties　and　distinct　applications　(smart　windows　and　dynamic　information　storage)　simply　by　adjusting　sintering　temperature　(y).　The　sample　SP-1180　exhibited　high　transparency　(∼62%　at　780　nm)　while　SP-1150　possessed　ultrafast　response　time　(3　s)　and　extremely　high　coloration　contrast　(ΔRI　=　91%).　More　importantly,　the　kinetics　of　photoreaction　could　be　modulated　by　varying　illumination　wavelength　and　time.　Furthermore,　a　new　anti-counterfeiting　or　optical　storage　method　was　designed　by　constructing　SP-1150　with　different　PC　properties.　The　encoded　or　stored　information　was　recorded　using　two　commercial　lasers　(370　&　405　nm　or　370　&　520　nm),　suggesting　that　the　security　level　of　this　anti-counterfeiting　design　could　be　significantly　improved.　This　work　will　drive　more　innovative　designs　in　smart　windows,　high-security　dynamic　anti-counterfeiting　and　optical　storage　applications　in　the　future.　©　2022　Elsevier　B.V.
