Fig. 3

a Typical pressure-dependent Raman spectra of the produced LuHxNy (sample-II) with a 633 nm laser excitation. The spectral curves (cycles) are deconvoluted by Gaussian fitting (solid lines). b Pressure-dependent shift of the fitted Raman peaks. c Pressure-dependent intensity of the Raman peaks of 124 cm−1, 147 cm−1, 194 cm−1, and 251 cm−1.
