Enhanced transmittance, mechanical durability, and anti-fingerprinting qualities of silver nanoparticles deposited onto glass substrates

Qualities such as an enhanced transmittance, mechanical durability, and resistance to fingerprinting were investigated for silver nanoparticles using a protective layer (fluoride/SiO2 films) deposited onto a silver nanoparticles (NPs)/SiO2/glass. The role of the protective layer in the enhancement of transmittance was investigated via localized surface plasmon resonance coupling and de-coupling using the protective layer/silver NPs/SiO2/glass. The protective layer deposited onto the dense and uniformly distributed silver NPs showed an enhanced transmittance of approximately 91%, compared with that of about 75% in samples without a protective layer. In addition, the protective layer showed effective anti-fingerprinting qualities and good mechanical durability after repeated swipes and touches.
