Synthesis and Characterization of Size-Controllable Titanium Dioxide Nanocolloids via Pulsed Laser Ablation in Distilled Water
Researchers used pulsed laser ablation in liquid (PLAL) to synthesize titanium dioxide nanocolloids by ablating a titanium target in distilled water with a 532 nm Nd:YAG laser. By varying laser fluence between 1.3 and 3.25 J cm⁻² and irradiation times from five to twenty minutes, they produced spherical TiO₂ particles ranging from 4.5 nm to 10.6 nm. The nanoparticles exhibited anatase‑phase band‑gap energies from 3.48 eV to 3.73 eV, confirming high purity and controllable optical properties. The study validates PLAL as an efficient, reagent‑free method for size‑tunable TiO₂ nanocolloids.
