“…Thus, the authors of ref described for the first time some structural parameters and color of the fluorescence emission of lanthanide gallium borates [LnGa 3 (BO 3 ) 4 with Ln = Y, Sm–Dy]. Kim et al investigated vacuum ultraviolet excitation and emission parameters of green-emitted phosphors with the chemical formula LnGa 3 (BO 3 ) 4 :Tb 3+ (Ln = Y, Gd) and concluded that these phosphors are excellent luminescent materials with plasma-discharge conditions, by converting VUV radiation to the visible light. Luminescence spectra of EuGa 3 (BO 3 ) 4 and HoGa 3 (BO 3 ) 4 are described in .…”

The present work presents the synthesis and growth conditions of (Eu,Tb):GdGa 3 (BO 3 ) 4 single crystals from a high-temperature solution Bi 2 O 3 − Ga 2 O 3 −B 2 O 3 -(Eu,Tb,Gd) 2 O 3 . Segregation coefficients of Eu 3+ and Tb 3+ doping cations were determined for the grown crystals, and their structural features, micromorphology, thermal characteristics, and luminescence properties were investigated.

“…Actually, it is well established that the properties of such luminescent nano-crystals depend on their structure, phase, dimensionality, shape, and size distribution in addition to their chemical composition. Actually, the industry demand is still very important in this field of advanced innovative materials due to their potential applications in many luminescent devises such as scintillators [1][2][3], Plasma Display Panels (PDP) [4][5][6][7][8][9][10][11][12][13]and Hg-free fluorescent lamp [14],Light-emitting diode LEDs [15].Among these materials, REBO 3 Orthoborates have attracted much more attention. Thanks to their special optical properties, low synthesis temperature, low toxicity, high stability, large band gap, strong vacuum ultraviolet (VUV) absorption and high ultraviolet and optical damage threshold [16][17][18][19].…”

Nano-sized Eu 3+ -doped GdBO 3 vaterite type nanophosphors have been synthesized successfully via acetylacetone assisted aqueous sol-gel route. Systematic investigation of the influence of Eu 3+ ion content and pH value of the suspension of precursors on structural, morphological and luminescence spectroscopic properties has been performed. X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, field emission-scanning electron microscopy (FE-SEM), Thermogravimetric and differential thermal gravimetry (TG/DTA), room temperature steady and time resolved photoluminescence (PL) spectroscopy techniques were employed to characterize the obtained powder samples. It has been found that the Eu 3+ ion content and pH value precursors suspension have important effect on the structural, morphology and emission properties. The XRD analysis reveals that GdBO 3 : 10% mol Eu 3+ synthesized at pH = 2 and pH = 10 exhibit the quasi-purest P6 3 /mmc vaterite structure. The vibrational absorption of (BO 3 ) 3group is assigned to the GdBO 3 with calcite type or other vaterite structure namely triclinic and monoclinic. The morphologies of GdBO 3 particles size increases with increasing of pH value. All sample present only the orange-red colors emission from 5 D 0 levels to the 7 F J levels (J = 0-3) of Eu 3+ ion. Furthermore, it was found that 10% concentration of Eu 3+ presents the quenching of emission in GdBO 3 . Also, it was that the emission intensity was affected by the pH value and sample with pH = 10 exhibits the highest emission intensity. The asymmetry ratio parameter R between red M. Seraiche a, *

“…[1,5] However, this requires high-performance blue, green, and red phosphors that can be excited by UV light, so nowadays attention has turned to the fabrication of blue, green, and red phosphors that are highly efficient, highly stable in chemical, and low thermal quenching. [6,7] The current commercial red phosphor for UV LEDs is Y 2 O 2 S: Eu 3+ . However, it is chemically unstable due to its sulfide nature, and it is uneconomical to use rare earth oxides.…”

The structure and photoluminescence (PL) properties of Sr3SiO5: Sm3+ and Li+-doped Sr3SiO5: Sm3+ red-emitting phosphors were investigated. Samples were prepared by the high-temperature solid-state method. PL spectra show that the concentration quenching occurs when the Sm3+ concentration is beyond 1.3 mol% in Sr3SiO5: Sm3+ phosphor without doping Li+ ions. The concentration-quenching mechanism can be explained by the electric dipole—dipole interaction of Sm3+ ions. The incorporation of Li+ ions into Sr3SiO5: Sm3+ phosphors, as a charge compensator, improves the PL properties. The lithium ions also suppress the concentration quenching in Sm3+ with concentration increased from 1.3 mol% to 1.7 mol%.
