The　YBCO　films　with　doped　YSZ　nanoparticles　have　been　prepared　successfully　by　metal　organic　doepositon　method　using　trifluoroacetates　(TFA-MOD)　through　dissolving　Zr　organic　salt　into　the　YBCO　precursor　solution.　The　doped　films　have　well　in-plane　and　out-plane　textures　detected　by　both　XRD　Phi-scan　and　omega-scan.　The　YSZ　nanoparticles　with　the　size　of　about　5　similar　to　15　nm　were　observed　on　the　surface　of　the　YBCO　films　using　both　FE-SEM　and　TEM.　By　comparing　the　superconducting　properties,　it　was　found　that　the　doped　YBCO　films　had　lower　T(c)　than　that　of　undoped　YBCO　films.　However,　as　increasing　the　applied　magnetic　field,　J(c)　of　the　doped　YBCO　films　were　much　better　than　that　of　undoped　one.　The　J(c)　was　as　higher　as　2.5　times　than　that　of　undoped　YBCO　film　at　77　K　and　1　T　applied　field.
