Dataset of UV-C Emitting Properties of Pr3+-activated Rare Earth Phosphates Driven by Structural Lattice Distortion Through Substitutional Doping Strategy
The data named as Figure3 are related to the X-ray diffraction (XRD) patterns acquired for Y1-xLaxPO4:Pr3+ upon varying the La concentration from 1-21 mol.%. The data named as Figure4 are associated with photoluminescence emission (PL) spectra for Pr3+-activated La (5 mol.%)-doped YPO4:Pr3+ (Pr3+ 3 mol.%) under the different excitation wavelength of 220, 223, 225, 228, and 230 nm. The data named as Figure5 are associated with photoluminescence emission (PL) spectra acquired for Pr3+-activated La (x mol.%)-doped YPO4:Pr3+ (Pr3+ 3 mol.%) as a function of La concentration varied from 0-25 mol.% (x = 0-0.25) under the excitation wavelength of 225 nm
Steps to reproduce
The photoluminescence (PL) emission spectra were recorded by PSI Instruments equipped with DarsaPro 5000 using a 500W Xenon lamp as an excitation source. Scanning electron microscope images were taken using Tescan Mira 3 LMU FEG, which was operated at an accelerating voltage of 10 kV. X-ray diffraction patterns were collected using the X-ray diffractometer of Rigaku D/Max-2200V in a 2 theta range from 20-60o; the X-ray source is based on Cu Kα radiation with corresponding wavelength of 0.15405 nm.
