Investigation of luminescence processes in Li6Gd(BO3)3:Eu3+ phosphor

Multicolor tunable bright photoluminescence in Ca2+/Mg2+ modified Eu3+ doped ZnGa2O4 phosphors under UV excitation for solid state lighting applications

“…The emission intensity is optimum for 0.1 mol% concentration of Eu 3+ ion. 44,45 As is seen from Fig. 7, the intensity I 5 D 0 / 7 F 2 [ I 5 D 0 / 7 F 1 .…”

Tunable emission from green to red in the GdSr2AlO5:Tb3+,Eu3+phosphorviaefficient energy transfer

“…The broad band from 200 nm to 250 nm centered at 220 nm is ascribed to the fd transitions of the Tb 3+ ions, whereas the excitation peaks at 275 and 310 nm originate from the transitions of 8 S 7/2 / 6 I 7/2 and 8 S 7/2 / 6 P 7/2 of the Gd 3+ ions, respectively. 30,31 The appearance of strong excitation sharp bands of Gd 3+ ions conrms that there is an efficient energy transfer from Gd 3+ to Tb 3+ . The emission spectra of the phosphor under 220, 275, and 310 nm excitation in the wavelength range from 400-650 nm are also depicted in Fig.…”

The Optical Properties of Dy³⁺ Doped LaPO₄ Phosphors Prepared by Solid State Reaction Method

“…These phosphors can be very easily employed in lighting display technology and various coating display illuminating applications. The overall SEM studies concluding us the phosphors can be grounded mechanically and sieved to get the uniform size to use as phosphors in devices like compact fluorescent lamps (CFL) and fluorescent lamps [FL][20,21].…”
