Time-resolved photoluminescence unlocks nanoscale insights into surface-modified metal oxide semiconductors

Semiconducting metal oxides like titanium dioxide (TiO) have emerged as essential materials due to their abundance, stability, and intriguing photophysical properties.

But there's a catch: Their surfaces, where most chemical interactions occur, often behave unpredictably, limiting their performance in applications ranging from photocatalysis to solar energy harvesting.

Researchers at the University of Delaware introduced time-resolved photoluminescence (TRPL) as a powerful and noninvasive optical tool to probe these coatings.

Time-resolved photoluminescence (TRPL) can be applied in ambient or controlled environments, making it suitable for in-situ and operando studies.

Beyond TiO, this methodology can be extended to a wide range of wide-bandgap oxides such as ZnO , SnO , and WO.
