A great difference has been found in the intensities of orthogonal circularly polarized components for a number of luminescence lines. The findings are explained by a mechanism of "mixing" of electronic states of the Tb3+ and Ho3+ ions in the matrix of the Y3Al5O12 garnet in an ...
The elemental composition and maps of the Y2-x-yO3:Hox=0.005,Yby=0.05films were obtained through the EDS analysis, Fig.5. All the expected elements (Y, O, Yb, and Ho) in the films were observed. Common impurities such as carbon (C) also appeared in the spectra, which probably could...
Ho3+ doping enhances the red emission level of the system and changes the characteristic green emission into red emission. Importantly, Ho3+ doping increases the difference in pumping time between green and red excited states. Under short pulse-width laser excitation, the red excited state does ...
The introduction of Ho3+ and Yb3+ ions as co-dopants into Y2O3 did not change the structure type, but a small shift towards high angles in the diffraction reflection peaks was observed with increasing Yb concentration (Figure 1b). The shift is attributed to the ionic radius difference ...

An identical fine structure of the hyperfine components is clearly observed in the absorption and PL spectra if x ≠ 0. Earlier, the structure observed in the absorption spectra was unambiguously ascribed to the isotopic disorder in the lithium sublattice26,27. Because of the difference in ...

Since the energy difference between the metastable state (5I6) and the ground state (5I8) of Ho3+ ions is close to the energy difference between ground state (2F7/2) and the excited state (2F5/2) of Yb3+ ions, Yb3+ can be a suitable donor in obtaining an efficient energy transfer...
The small Rho GTPase acts as a molecular switch in eukaryotic signal transduction, which plays a critical role in polar cell growth and vesicle trafficking. Previous studies demonstrated that constitutively active (CA) mutant strains, of MoRho3-CA were d
