Hydrothermal synthesis and photoluminescence of the monophosphate LaPO4:Eu(5%)

Synthesis and characterization of Tb3+ activated La0.6Y0.4PO4 phosphor

“…The figure shows the FTIR spectrum of La 0.6 Y 0.4 PO 4 : Tb (0.5%). From FTIR spectrum, it is observed that vibrations, respectively) [16]. Neither Tb impurity, nor oligoperoxides affect the structure and the position of these bands.…”

Preparation and properties of the green-emitting phosphors NaCa0.98−xMgxPO4:

“…The FTIR spectra of NaCa 0.90 Mg 0.08 PO 4 :Eu 2þ 0:02 and NaCa 0.98 PO 4 :Eu 2þ 0:02 display only the characteristic bands of the orthophosphates [20,21] (Fig. 2).…”

Synthesis, characterization and DFT calculations of electronic and optical properties of YbPO 4

“…Lanthanide monophosphates (LnPO 4 ) were extensively used as host materials producing luminescent materials such as fluorescent lamp, lighting phosphor, optical amplifiers and lasers based on their optical, magnetism and electrical properties, high quantum efficiency and stability at high temperature [1][2][3][4][5][6][7][8]. Rare earth monophosphates LnPO 4 exist in nature as the monoclinic monazite type (for La to Gd) and the quadratic xenotime type (for Tb to Lu).…”

“…The linear photon-energy-dependent dielectric functions, conductivity and some optical constants such as refractive index, reflectivity and absorption coefficients were determined. The calculated total and partial densities of states indicate that the top of valance band is built upon O-2p states with P-3p states via σ (P-O) interactions, and the conduction bands mostly originate from Yb-5d states.Lanthanide monophosphates (LnPO 4 ) were extensively used as host materials producing luminescent materials such as fluorescent lamp, lighting phosphor, optical amplifiers and lasers based on their optical, magnetism and electrical properties, high quantum efficiency and stability at high temperature [1][2][3][4][5][6][7][8].
