Optical CO<sub>2</sub> Gas Sensing Based on TiO<sub>2</sub> Thin Films of Diverse Thickness Decorated with Silver Nanoparticles

<div>Color change during the synthesis of AgNPs depicting different stages of the reaction. (a) Dissolving of silver precursors into water remained transparent. (b–d) Introduction of the reducing agent (trisodium citrate) caused the reduction of precursors as appeared in color change from transparent to greenish yellow.</div>
