Abstract：

Rare　earth　Tb3+　doped　(K0.465Na0.465Li0.07)(Nb0.93Bi0.07)O3　(KNNLB-x%Tb)　lead-free　transparent　ferroelectric　ceramics　were　designed　and　prepared.　The　effects　of　Tb3+　on　phase　structure,　microstructure,　optical　transmittance,　photoluminescence,　and　photochromic　behaviors　were　studied.　Although　two　ferroelectric　phases　coexist,　the　optical　transmittance　can　reach　the　high　value　of　74%　in　the　visible　light　region　because　of　the　fine　grains,　dense　ceramic　microstructure,　large　optical　energy　band　gap,　and　relatively　high　symmetry　of　coexisting　ferroelectric　phases.　In　addition,　Tb3+　works　as　a　luminescent　center,　and　the　reversible　photochromic　modulation　is　achieved　by　alternate　stimulation　of　illumination　and　heat　treatment.　Meanwhile,　the　luminescence　contrast　can　be　improved　under　in　situ　electric　field　stimulation　due　to　the　easy　change　of　lattice　symmetry　in　coexisting　ferroelectric　phases.　The　generation　of　color　centers　after　illumination　and　the　local　crystal　field　around　the　luminescent　center　caused　by　in　situ　electric　field　contributes　to　above　phenomena.　These　ceramics　exhibit　the　great　potential　in　optical　data　storage　and　anticounterfeiting.
