Abstract
Emission spectral results of Pr3+ & Ho3+ ions
doped Ca4GdO(BO3)3 powder phosphors are reported here.
XRD, SEM and FTIR measurements have been carried out
for them. The emission spectrumof Pr3+: Ca4GdO(BO3)3 has
shown an emission transition 1D2 ? 3H4 at 606 nm with
kexci = 480 nm (3H4 ? 3P0) and Ho3+: Ca4
GdO(BO3)3
phosphor has shown an emission transition 5S2 ? 5I8
at 549 nm with kexci = 447 nm (5I8 ? 5F1). Emission performances
of these two phosphors have been explained in
terms of energy level diagrams
