“…Mokoena et al [33] reported on the luminescence properties and the particle morphology of the Ca 3 (PO 4 ) 2 :Gd 3+ , Pr 3+ phosphor. Finally, luminescence and electron paramagnetic resonance (EPR) studies of the BaZrO 3 :Gd 3+ phosphor have been reported by Singh et al [34].…”

A BaAl 2 O 4 :Gd 3+ phosphor was successfully prepared using a combustion technique. An X-ray diffraction pattern was used to characterize the resultant phosphor, and the photoluminescence (PL) of the prepared BaAl 2 O 4 :Gd 3+ was studied. Under a 273-nm excitation, the main emission peak of the phosphor is located at 314 nm, and this is attributed to the 6 P 7/2 → 8 S 7/2 transition of Gd 3+. Electron paramagnetic resonance (EPR) spectrum appears to be U-shaped, and lines are evident at g eff ∼ 2.14, 4.56 and 6.75. The PL and EPR analyses indicate the presence of Gd as Gd 3+ in this sample.

Study. -BaZrO 3:Gd is prepared by combustion of an aqueous solution of Ba(NO 3)2, ZrO(NO3)2, Gd(NO3)3, and urea (1. 80 C, 30 min; 2. muffle furnace, 550 C) which produces a foam-type fluffy mass that subsequently is calcined in air (alumina crucible, 1100 C, 3 h) for the removal of byproducts and the reduction of internal strain. EPR spectra of un-doped and Gd-doped samples are presented and discussed in detail. The excitation spectrum exhibits a dominant band with a maximum at 275 nm. Upon excitation at 275 nm, the emission spectrum exhibits a well-defined UV-B emission band with a maximum at 314 nm corresponding to the 6 P7/2 8 S7/2 transition. The phosphor is discussed as a promising candidate for applications in phototherapy lamps. -(SINGH*, V.; SIVARAMAIAH, G.; RAO, J. I.; WATANABE, S.; RAO, T. K. G.; JAGTAP, S. S.; SINGH, P. K.; J.
