Developing　multi-functional　single　buffer　layer　is　one　of　the　most　important　challenges　for　simplification　of　coated　conductors　configuration.　La-doped　CeO2　films　were　prepared　by　chemical　solution　method.　And　surface　morphology　and　texture　quality　of　the　La-doped　CeO2　films　were　Investigated　in　details.　The　results　show　that　the　as-obtained　pore-free　Ce0.9La0.9O2　film　are　epitaxially　deposited　oil　the　textured　NiW　substrate.　The　120nm　thickness　Ce(0.9)Lao(0.1)O(2),　film　is　obtained　though　multi-coating　route.　The　YBCO　film　With　T-co　=　90.5　K,　which　is　deposited　on　Ce0.9La0.1O2/NiW　metallic　template　by　PLD　method.　It　suggects　that　Ce0.9La0.1O2　film　prepared　by　chemical　solution　route　have　a　promising　prospect,　for　the　simplification　of　coated　conductors　configuration
