A new sub-nanosecond LED at 280 nm: application to protein fluorescence

Birch, D.J.S. and McGuiness, C.D. and Sagoo, K. and McLoskey, D. (2004) A new sub-nanosecond LED at 280 nm: application to protein fluorescence. Measurement Science and Technology, 15 (11). pp. 19-22. ISSN 0957-0233

We demonstrate measurement of the intrinsic fluorescence decay of a protein excited with a new and inexpensive optical source based on a light emitting diode (LED) giving 600 ps pulses at ∼280 nm. We believe this source will offer significant new capabilities for fluorescence research and development.
