Abstract: IN THE LAST DECADE OR SO, SIGNIFICANT PROGRESS HAS BEEN MADE WITH REGARD TO THE DESIGN, SYNTHESIS, AND UTILIZATION OF NANOSTRUCTURE MATERIALS. AMONG VARIOUS SYSTEMS, PLASMONIC METAL/SEMICONDUCTOR NANOCOMPOSITES HAVE RECEIVED BROAD INTEREST DUE TO THEIR UNIQUE PROPERTIES AND MULTIFUNCTIONAL APPLICATIONS. TO EXPLAIN THE RELATIONSHIP BETWEEN PLASMONIC METAL AND SEMICONDUCTOR, THE ELECTRON INJECTION MECHANISM HAS BEEN PROPOSED. IN THIS THESIS, WE PREPARED METAL/TIO2 AND METAL/SNO2 NANOCOMPOSITES TO INVESTIGATE THEIR APPLICATIONS BASED ON THE ELECTRON INJECTION MECHANISM. METAL/TIO2 NANOCOMPOSITES WERE USED AS PHOTOCATAYSTS FOR DYE DEGRADATION. FURTHER, AU NR/TIO2 WITH SPR BAND CENTERED AT 808 NM WAS USED AS PHOTOSENSITIZER FOR NEAR-IR LIGHT INDUCED PHOTODYNAMIC THERAPY. METAL/SNO2 NANOCOMPOSITES WERE USED TO CATALYZE THE 4-NITROPHENOL REDUCTION EXPERIMENTS DUE TO THE MESOPOROUS AND PERMEABLE PROPERTIES OF SNO2 SHELL. AND THEN, THE DEPOSITION OF AG ON AUNR/SNO2 WAS CONTROLLED BY LIGHT I
