Nd3+:GdScO3 crystal field energy level and fitting

Cut the grown Nd3+:GdScO3 crystal into 1.5 mm thin slices, polish both sides, and achieve a smoothness of 5-10. Then test the absorption spectrum of the Nd3+:GdScO3 crystal.

The instrument measuring the spectrum is the Perkin Elmer Lambda-950 UV/VIS/NIR spectrophotometer, with a step size of 0.2 nm and a measurement range of 250-2650 nm. This dataset includes the absorption spectra measured at low temperatures (8 K) as shown in Figure 1 (250-500 nm), Figure 2 (500-700 nm), Figure 3 (700-1000 nm), and Figure 4 (1000-2650 nm); Use the FLSP-920 spectrometer to test the room temperature emission spectrum of the sample, shown in Figure 5.
