“…Bi 3.8 Eu 0.2 MgO 4 (PO 4 ) 2 showed CIE coordinates ( x = 0.5964, y = 0.3905) and QE of 66%, which makes it a potential nano phosphor for solid-state lighting (SSLs) and imaging applications. 205 In the color-tunable phosphor K 5 Y(P 2 O 7 ) 2 :Eu (KYP:Eu), the Eu 2+ dopants may occupy K + or Y 3+ sites. This leads to warm white light emission at RT (bands at 430–520 nm are due to Eu 2+ in K + sites, and the bands at 530–720 nm are attributed to Eu 2+ in Y 3+ sites).…”

“…In recent times, inorganic phosphors doped with lanthanide ions have attracted much attention due to their potential applications as phosphors, laser materials, or solid-state lighting [1][2][3][4][5][6]. The current white-light-emitting diodes (W-LEDs) suffer from a lack of red light, therefore, red phosphors are sought to fill deficiency.…”

KMeY(PO4)2:5% Eu3+ phosphates have been synthesized by a novel hydrothermal method. Spectroscopic, structural, and morphological properties of the obtained samples were investigated by X-ray, TEM, Raman, infrared, absorption, and luminescence studies. The microscopic analysis of the obtained samples showed that the mean diameter of synthesized crystals was about 15 nm. The KCaY(PO4)2 and KSrY(PO4)2 compounds were isostructural and they crystallized in a rhabdophane-type hexagonal structure with the unit-cell parameters a = b ≈ 6.90 Å, c ≈ 6.34 Å, and a = b ≈ 7.00 Å, c ≈ 6.42 Å for the Ca and Sr compound, respectively. Spectroscopic investigations showed intense 5D0 → 7F4 transitions connected with D2 site symmetry of Eu3+ ions. Furthermore, for the sample annealed at 500 °C, europium ions were located in two optical sites, on the surface of grains and in the bulk. Thermal treatment of powders at high temperature provided better grain crystallinity and only one position of dopant in the crystalline structure. The most intense emission was possessed by the KSrY(PO4)2: 5%Eu3+ sample calcinated at 500 °C.

“…Recently there has been rapid growth in research of phosphor materials for its wide range of luminescence applications in solid-state lighting devices [1,2]. Of particular interest, orthophosphates with formula of ABPO 4 (with A= alkaline metals and B = alkaline earth metals) has attracted much interest because of its intense luminescence emissions in the visible region and facile methods of preparation making them potential candidates for applications in colour display devices [3,4].…”

Researchers are in active pursuit of scintillator materials for diagnostic applications in medical science. Such pursuits are only achieved through experimental investigations of phosphor materials. To address this issue, we focused on the comparative photoluminescent behaviours of inorganic orthophosphates, NaMPO 4 :xCe 3+ (M = Ca, Ba, Sr, Mg), synthesized via the traditional solid-state reaction method and the combustion method. The combustion method is a simple and rapid method of producing a variety of nanosized particles (use of nitrates, fuels, etc.), while the solid-state reaction method (use of metal oxides) focus on a gradual heating of the powders from room temperature to 900 °C (to allow for interdiffusion of cations). Various techniques such as XRD, SEM and PL were used to characterize these phosphor materials. Further, the CIE (Commission international de Iéclairage) plots were then obtained using the PL data to compare colour tuning in each case. A comparison of the results reveals that the NaBaPO 4 :xCe 3+ phosphor displayed the best photoluminescence behaviour for an optimal concentration of x = 0.5 mol % using the combustion method of synthesis, on the other hand using the solid-state reaction method, the best photoluminescence was obtained for an optimal concentration of x = 1 mol % for the same material. In each of the above cases, the PL emission spectra was due to the 5d→ 4f transition of the Ce 3+ ions. The results points to the fact the Ce 3+ emissions in the NaBaPO 4 :xCe 3+ ion occurs for a higher concentration in the solid-state method and for a lower concentration in the combustion method scenario (quenched for same concentration in the combustion method). This could be attributed to the slow diffusion of ions in the solid-state reaction method, compared to the fast combustion in the combustion method (600 °C).
