Ultra-low intensity UV detection using partitioned mesoporous TiO₂
In brief
Dividing a porous TiO₂ film into narrow partitions makes it detect very faint ultraviolet light about 100,000 times better.
Key results- Five orders of magnitude enhancement in ultra-low-intensity UV detection.
- Responsivity of about 0.1 A/W at 100 µW/cm² and 0.01 A/W at 14 µW/cm².
- The partitioned film behaves as a quasi-one-dimensional transport medium.
