The quantum efficiency measured results of Eu 3+ -doped Y 2 (W x Mo 1−x O 4 ) 3 (x = 0, 0.25, 0.50, 0.75, and 1.0) reveal a decreasing trend in η I Q E , while the η E Q E initially increases and then decreases with an increase in calcination temperature.
Inter-residue H-bonds between non-adjacent backbone amide NH and C=O motifs lead to the well-known secondary structures of helices, turns and sheets, but it is recognized that other H-bonding modes may be significant, including the weak intra-residue H-bond (called a C5 H-bond) that implicates the NH and C=O motifs of the same amino acid residue.
