Description
Summary:[Display omitted] •UV-switchable reducing agent used to decorate Ag nanoparticles on TiO2 nanotubes.•Low turn-on field 2.7V/μm for Ag/TiO2 nanocomposite has been found.•Low turn-on field attributed due to nanometric feature of Ag nanoparticles.•High current density of 1.24mA/cm2 has been found. High current density of 1.24mA/cm2 was drawn at an applied field of 4.4V/μm from Ag/TiO2 nanocomposite. Also the turn-on field has been reduced from 3.9V/μm to 2.7V/μm for the emission current density of 10μA/cm2. Ag/TiO2 nanocomposite was synthesized by using UV-switchable reducing agent. TiO2 nanotube wall was decorated by Ag nanoparticles with average diameter of 17nm. To the best of our knowledge this is the first report on the field emission studies of Ag/TiO2 nanocomposite. Simple synthesis route coupled with superior field emission properties indicate the possible use of Ag/TiO2 nanocomposite for micro/nanoelectronic devices.
