摘要：

Nb5+　was　doped　into　YBCO　precursor　solution,　and　Ba2YNbO6　(BYNO)　nanoparticles　can　be　found　in　the　YBCO　film　with　both　epitaxial　and　random　orientations.　The　nucleation　process　of　the　YBCO/BYNO　composite　film　was　studied　by　2D-XRD.　It　indicates　that　the　low　temperature　decomposition　of　the　doped　film　has　no　difference　with　the　pure.　The　BYNO　nucleates　between　750　degrees　C　and　775　degrees　C.　In　addition,　epitaxial　and　random　oriented　BYNO　coexist　in　the　precursor　film.　The　nucleation　of　the　YBCO　takes　place　at　820　degrees　C,　and　all　of　them　express　(00l)　orientation.　The　existence　of　the　BYNO　doesn＇t　affect　the　YBCO＇s　orientation.　The　function　of　the　nucleation　process　has　also　been　analyzed.
