摘要: Non-hydrolytic sol-gel process was employed to prepare Eu3+-doped and silver nanoparticles/nanowires (Ag NP/NWs) co-doped SiO2-TiO2-ZrO2 ternary matrix. XRD, TEM, SAED analyses revealed that the matrix is of amorphous nature even crystalline are embedded. The formation further evidenced by characteristic peaks in FTIR spectrum EDS analysis. emission intensity enhanced sixfold for Ag NPs eightfold NWs embedded probably due Surface Plasmon Coupled Emission (SPCE). Above critical concentration 1 wt.% NP 1.5 wt.% NW, starts diminish because quenching effects. CIE chromaticity studies confirm addition NP/NWs into does not alter color coordinates purity present system. These Eu3+-Ag NP/NWs-doped systems could be used as a promising material efficient red light emitting sources, bio-detection, plasmonic sensor applications.
