A　trade-off　contradictory　relationship　between　texturization　and　optical　transparency　exists　in　ferroelectric　ceramics,　so　to　achieve　transparency　in　textured　ferroelectrics　is　quite　difficult.　Here,　Er3+　and　LaBiO3　co-modified　(K0.5Na0.5)NbO3　(1Er-KNN-yLB)　transparent　textured　ceramics　were　successfully　prepared　by　the　tape-casting　method.　Doping　of　LaBiO3　enables　the　textured　ceramics　to　exhibit　excellent　up-conversion　photoluminescence　properties,　and　the　red　emission　is　significantly　improved.　Meanwhile,　with　certain　amount　of　LB　content,　the　textured　ceramics　show　nanoscale　grains　and　approaching　pseudo-cubic　phase,　resulting　in　high　density　and　obvious　relaxor-like　behavior.　This　result　indicates　high　local　symmetry　and　less　light　scattering　centers　within　the　textured　ceramics,　finally　bringing　about　enhanced　optical　transparency,　with　the　highest　transmittance　of　∼　39%　in　the　visible　region　at　y　=　0.025.　Additionally,　the　observable　piezoelectric　and　ferroelectric　performances　were　obtained.　These　multifunctional　properties　endow　KNN-based　textured　ceramics　with　promising　application　prospects　in　optoelectronic　devices.　©　2022　Elsevier　B.V.
