Data source (4) for "Slow optical response of semi-insulating GaN film studied by terahertz emission and photoluminescence spectroscopy"

Raw data for Fig9a in "Slow optical response of semi-insulating GaN film studied by terahertz emission and photoluminescence spectroscopy"We measured the PL time variation for five times, named "Fig9a_timevariation1–5"."Fig9a_timevariation**_3s_times_ (12)" means 3 * 12 = 36s after starting excitation.Fig9a shows the spectra averaged at each time point.
