Abstract：

The　(K0.5Na0.5)0.95Li0.05Nb0.95Bi0.05O3-1mol%　Er2O3　transparent　ceramics　were　prepared　by　a　pressureless　sintering　method.　The　fabricated　transparent　ceramics　not　only　exhibit　high　optical　transmittance　(85.3%)　due　to　dense　microstructure　(nanoscale　size　grains),　but　also　show　the　photochromism-induced　light　scattering　and　reversible　upconversion　(UC)-switching　properties　by　visible　light　irradiation.　Upon　407 nm　light　irradiation,　the　optical　transmittance　intensity　is　significantly　decreased,　showing　a　strong　light　scattering　(ΔAbs = 28.3%).　The　light　scatting　degree　can　be　quantitatively　reflected　by　Er3+　ion　UC　emission,　and　could　be　recovered　to　its　initial　optical　transmittance　based　on　photochromic　reactions.　Meanwhile,　the　transparent　ceramic　is　found　to　maintain　good　energy　storage　properties　with　higher　W　(5.87 J/cm3)　and　Wrec　(1.96 J/cm3)　under　a　higher　electric　field　of　260 kV/cm.　These　results　suggest　that　Er3+　doped　(K0.5Na0.5)NbO3　transparent　ceramics　are　promising　for　the　modulation　of　light　scattering　and　the　design　of　photoelectric　multifunction　devices.　©　2019　The　American　Ceramic　Society
