Particularly, the Cr3+ ions with a unique 3d3 electron configuration are easy to produce broadband NIR luminescence when they are situated in a weak octahedral crystal field environment, matching well with the commercial blue chip. For instance, Xie et al. synthesized La2Mg1-0.5xZr1-0.5XO6: ...
Moreover, the emission from Mn4+ ions with 3d3 electron configuration is sensitive to the host matrix and exhibits an SR of 0.34% K−1 in Gd2ZnTiO6 phosphors [22]. To the best of our knowledge, Cr3+-doped luminescent materials have seldom been reported for bandwidth-based optical ther...

along with the variation in trap concentration and type, which is determined by the dynamic variation of defect annihilation and creation, are both related to the phosphorescence duration of Zn(2-x)Al2xSn(1-x)O4phosphors, as demonstrated by the thermoluminescence (TL) spectra and electron spin...
A spectroscopic investigation of Y3Al5O12:Pr3+ in translucent ceramic form: Crystal field analysis assisted by configuration-interaction This paper presents an investigation of Pr 3+ doped in the D 2 site of Y 3 Al 5 O 12 (YAG), for the first time on a translucent ceramic sample free ...
Besides the bond geometry changes, tilting of the FeO6 octahedra affects the one-electron bandwidth of the 3d electron in a way that it gets smaller with the decrease in ionic radius. The changes from G-type antiferromagnetic, with the magnetic moment in the "a" direction to ferromagnetic, ...
The electronic configuration is the distribution of electrons in the orbitals and principal shells around the atom or a molecule. The electrons are distributed according to Aufbau's rule, Hund's rule and Pauli's exclusion principle.Answer and Explanation: The atomic number of chromium is 2...
