摘要：

A　simple　method　to　optically　synthesize　Ag　nanoparticles　in　Ge2Sb2Te5　phase　change　matrix　is　described.　The　fine　structures　of　the　locally　formed　phase　change　chalcogenide　nanocomposite　are　characterized　by　high-resolution　transmission　electron　microscopy.　The　formation　mechanism　of　the　nanocomposite　is　discussed　with　temperature　evolution　and　distribution　simulations.　This　easy-prepared　metal　nanoparticle-embedded　phase　change　microstructure　will　have　great　potential　in　nanophotonics　applications,　such　as　for　plasmonic　functional　structures.　This　also　provides　a　generalized　approach　to　the　preparation　of　well-dispersed　nanoparticle-embedded　composite　thin　films　in　principle.　(C)　2012　Elsevier　B.V.　All　rights　reserved.
