 * "For measurements of excitation spectra the excitation wavelength was scanned from 230 to 380 nm at the same scanning rate, and emission monitored at 450 or 506 nm."

https://iopscience.iop.org/article/10.1149/1.2055033/meta Note also that the excitation is the 'input' to the sample; the emission is the 'output' that's read. Other similar examples are available, but I think the above is a quite clear illustration. —DIV (1.145.128.215 05:26, 12 January 2024 (UTC))
