"R% Two TAB-separated columns start from the third line: The first column contains the wavelength of the incoming light (excitation wavelength) in nanometers. The second column contains the intensity of registered light, measured in the reflectance mode, with respect to the BaSO4 (barium sulphate) reference blank sample Plotting tool: a simple plotting script relying on Gnuplot is provided: plot_spectra.gnuplot (Usage: gnuplot -p -c plot_spectra.gnuplot in the folder with the data files) List of data files and corresponding samples: toyoboQ51_sanded_DR.txt: sample of a Teonex Q 5100 / 25 micron foil from Toyobo, Inc., pressed against the BaSO4 blank sample pvn_sigma_baso4.txt: poly(2-vinyl naphthalene) powder from Merck, 𝑀𝑛 = 175,000 PEN_white_ichp2.txt: sample of poly(ethylene naphthalate) foil custom-synthesized [1] at Łukasiewicz – Industrial Chemistry Institute, pressed against the BaSO4 blank sample p11013-2vn_DR.txt: poly(2-vinyl naphthalene) powder from Polymer Source, Inc., 𝑀𝑛 = 91,400 (product ID 11013) p10928-2vn.txt: poly(2-vinyl naphthalene) powder from Polymer Source, Inc., 𝑀𝑛 = 48,000 (product ID 10928) esrtpb_2pac_DR.txt: a sample of 1,1,4,4-tetraphenyl-1,3-butadiene (TPB)-coated 3M ESR foil (from a batch used in Ref. [2] and [3]) Cryogenic fluorescence measurements data Dataset creation date: 22 May 2024 (pvn.txt) and 29 May 2024 (tpb.txt) Methodology: data were collected using a custom test stand described in Ref. [2]. Data format specification: File type: ASCII Each file contains one line per event. Each line contains one value of the integrated event charge (in arbitrary units), obtained by integrating waveforms acquired with the CAEN V1725 digitizer.
