Fascinating functional properties of Mn:Gd2O3 nanocrystalline phosphor

The magnetic measurement showed negative values for curie paramagnetic temperatures, θ, which indicates an antiferromagnetic interaction between the magnetic ions in Mn:Gd2O3. PL spectra showed a series of emission lines in the room temperature fluorescence measurements under UV excitation (220 nm). The observed emission lines are stokes-shifted and the non-linearity optical phenomenon is confirmed. Further, the emission lines are slightly shifted with Mn concentration (x). The blue emission around (390-402) nm was appeared due to Mn doping. Because of its fascinating properties, Mn:Gd2O3 is recommended for fuel cells, photocatalytic, and biomedical applications.
