Pedagogy
Teaching and instruction happen both inside and outside the classroom. Often, to succeed in undergraduate, graduate, or postdoctoral studies, one must supplement in-class instruction with independent learning. This can be useful in that supplemental resources lend new perspectives on a topic, but practically speaking it is useful to have access to resources that can be accessed digitally and asynchronously.
To that end, I have put together several introductory video lectures on spectroscopic techniques that are central to renewable energy research and photocatalysis; namely, time-resolved photoluminescence (TRPL) and transient absorption spectroscopy (TAS). Information on these techniques are hard to come by. These videos build from the core concept, give input on data interpretation, and literature examples that highlight what the techniques can tell us about materials.
If you watch the videos and have questions, please feel free to reach out.
This video describes the fundamental principle of time resolved photoluminescence using the most common technique -- Time Correlated Single Photon Counting (TCSPC). Included at the end are literature examples that show the breadth of what TCSPC can tell us.
This video describes the fundamental concept of transient absorption spectroscopy (TAS), including literature examples that highlight what can be gleaned from TAS.
This video describes the instrumentation of nanosecond and femtosecond transient absorption spectroscopy (TAS).
