“…Green emission is dominant due to the presence of Tb 3+ dopant. A similar emission is published for Tb doped phosphors [21,22]. Figure 5 shows that blue emission (5D3→7FJ) intensity is decreased and green emission (5D4→7FJ) intensity is increased with increasing concentration of Tb 3+ .…”

The well-known solid-state reaction method is used for the synthesis of Tb doped LuGd2Ga2Al3O12 phosphor. XRD and SEM techniques are used for the phase and structural morphology of the synthesized phosphor. UV, X-ray and proton induced spectroscopy is used to study the luminescence properties. LuGd2Ga2Al3O12:Tb3+ phosphor shows its highest peak in green and blue region. The two major emission peaks correspond to 5D3→7FJ (at 480 to 510 nm, blue region) and 5D4→7FJ (at 535 to 565 nm, green region). Green emission is dominant; therefore, it may be used as an efficient green phosphor. The absorption spectra of the synthesized material matches well with the spectra of light emitting diodes (LEDs); therefore, it may have applications in LEDs. X-ray spectroscopic study suggests that this phosphor may have uses in medical applications, such as X-ray imaging. The synthesized phosphor exhibits 81% efficacy in comparison to the commercial plasma display panel material (Gd2O2S:Tb3+). The Commission Internationale de l’Eclairage (CIE) chromaticity diagram is obtained for this phosphor. The decay time of ms range is measured for the synthesized phosphor.

“…Normally oxide samples require high calcination temperature to get single pure phase. Table 1 shows Tb 3+ doped different oxide hosts prepared at different calcination temperatures [35][36][37][38][39][40]. In the present investigation, the PXRD patterns of ZrO 2 :Tb 3+ (1-5 mol%) were well indexed to tetragonal phase (JCPDS 81-1544).…”

ZnO nanorods (NRs)/Fe 3 O 4 quantum dots (QDs) nanocomposites were successfully synthesized via an easy electrostatic self-assembly method. The results showed that Fe 3 O 4 QDs with an average diameter of 4-5 nm were well dispersed on the surface of the ZnO NRs with an average diameter of 118 nm, forming ZnO NRs/Fe 3 O 4 QDs nanocomposites. The ZnO NRs/Fe 3 O 4 QDs nanocomposites were used as photocatalysts for the degradation of Rhodamine B under solar light irradiation. The kinetic rate constant of the ZnO NRs/Fe 3 O 4 QDs nanocomposites was two times higher than that of the ZnO NRs. The enhanced photocatalytic property was attributed to the extended absorption spectrum of the nanocomposites.
