“…X-ray and proton induced emission spectra are shown in Figure 8 whereas UV-induced emission spectrum is shown in Figure 5. All three emission spectra are very similar and matches well with the literature [26,27]. This comparison shows that the emission properties do not depend on the excitation source.…”

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.

“…5 In the field of luminescent materi-als, A 2 BSbO 6 (B stands for rare-earth elements) phosphors have low symmetry and high coordination numbers, which are suitable host materials for rare-earth ions incorporating as well as their photoluminescence (PL). Recently, Eu 3+ -doped A 2 BSbO 6 phosphors have been studied extensively, which currently exhibit remarkable thermal stability, such as Ba 2 GdSbO 6 :Eu 3+ , 6 La 2 LiSbO 6 :Eu 3+ , Bi 3+ phosphors, 7 and Eu 3+ -activated Sr 2 InSbO 6 phosphors. 8 Furthermore, Mn 4+ -doped A 2 BSbO 6 phosphors have been considerably explored due to the admirably local structure [SbO 6 ] availing Mn 4+ to substitute.…”

A multifunctional double-perovskite-type Ca 2 LnSbO 6 (Ln = La, Y, Gd, and Lu) phosphors with Eu 3+ and Mn 4+ co-doped were successfully synthesized and designed to simultaneously apply to temperature sensing and plant growth LED. With temperature varying from 303 to 523 K, the integrated intensity of Mn 4+ ions ( 2 E g → 4 A 2g ) markedly decline swifter comparing to Eu 3+ ions ( 5 D 0 → 7 F 2 ) due to the thermal quenching effect. It implies that Mn 4+ is susceptive to the temperature in this work. Eu 3+ exhibits high heat resistance, which can be selected as a calibration parameter for the fluorescence intensity ratio temperature sensor. The maximum relative sensitivity (S r ) values of Ca 2 LnSbO 6 :1%Eu 3+ , 0.5%Mn 4+ (Ln = La, Y, and Gd) phosphor are estimated as 2.19% K −1 at 443 K, 1.68% K −1 at 503 K, and 1.80% K −1 at 483 K, respectively. They are superior to many recent emerging phosphors. Moreover, upon 365 nm excitation, Ca 2 LnSbO 6 :1%Eu, 0.5%Mn (Ln = La, Y, Gd, and Lu) phosphors display a wide red emission peaking at 696, 680, 677, and 684 nm, respectively. They come from the overlapped of 2 E g -4 A 2g of Mn 4+ and 5 D 0 -7 F 4 transition of Eu 3+ . Their full widths at half maximum are 34, 35, 35, and 29 nm, respectively. They are all perfectly overlapping the absorption curves of chlorophyll a and chlorophyll b, and their fabricated red phosphor-converted light-emitting diode device ulteriorly corroborated the promising applications for plant growth. Markedly, the systematic analysis of their crystal chemistry and site preferentially occupancy is first reported and discussed by the bond valence theory.

“…25,26 Moreover, energy transfer from Bi 3+ to rare earth activators (such as Eu 3+ , Dy 3+ , Pr 3+ , Tb 3+ , and Sm 3+ ) may occur in certain single-phase hosts, which broadens its luminescence characteristics and potential applications. [25][26][27][28][29][30][31][32][33][34][35] An appropriate host matrix is another key factor to determine the luminescent property of a material. Niobates with the formula RENbO 4 (RE = Y, La, Sc, Gd, and Lu) have extensive potential for anti-ferroelectric, field emission display, solidstate white-light lighting and photovoltaic applications due to their excellent physical, chemical, mechanical, and thermal resistance.…”
