Data source (3) for "Slow optical response of semi-insulating GaN film studied by terahertz emission and photoluminescence spectroscopy"

Raw data for Fig7b in "Slow optical response of semi-insulating GaN film studied by terahertz emission and photoluminescence spectroscopy"We measured the PL time variation for four times, named "Fig7b_timevariation1–4"."Fig7b_timevariation**_3s_times_ (12)" means 3 * 12 = 36s after starting excitation.Fig7b shows the spectra averaged at each time point.
