Transparent TiO2 thin films coated with Ag NPs were synthesized using two industrially applicable techniques,
pulsed laser ablation (PLAL) and spray pyrolysis without using high vacuum. These transparent thin films were
deposited on glass in order to generate glass materials with photocatalytic and antimicrobial properties and a
minimum loss of transparency. The structural, morphological and optical properties of the thin films were
examined using Grazing incidence X-ray diffraction (GIXRD), Raman spectroscopy, Scanning electron microscopy (SEM) and ultraviolet–visible spectroscopy. Transmission electron microscopy (TEM) was used to identify
the NPs on the TiO2 surface. The transmittance value for the thin films was greater than 80%.The thin films thus
synthesized were then assessed to determine their photocatalytic capacity by monitoring the degradation of
Rhodamine B (RhB) under UV light irradiation. Ag NPs on the TiO2 surface ensures an improvement in the
photocatalytic properties, with a 99% degradation of RhB in 210 min under UV light. In addition, these transparent thin films showed high antimicrobial activity on Gram-negative bacteria when irradiated by UV light for
4 h, killing 93% of these bacteria. [-]
