Investigation of structural and luminescent properties of Pr3+ activated CsGd(WO4)2 by sol–gel synthesis

Structural Characteristics and Thermodynamic Functions of Compounds Ba(La1–xPrx)2WO7 (x from 0.005 to 0.05)

“…This circumstance makes praseodymium-based compounds important laser and optical materials. 5,8 The luminescence intensity depends on the praseodymium content in a variable manner, for example, in the case of xPr 3+ /NaGd(WO 4 ) 2 reaches a maximum at a concentration of about 3.5 mol % Pr. 9 The properties of such compounds in addition to the chemical composition are also determined by the crystal structure.…”

“…Thus, there are a fairly large number of works describing the properties of compounds doped with praseodymium. As a rule, in the main majority they deal with the luminescent properties, − although there are also publications considering the investigations that have been carried out by differential thermal analysis and thermogravimetry. , The latest work also includes studying the magnetic properties of the compounds doped with lanthanides by the electron paramagnetic resonance method.…”

“…The investigations describing tungstates doped with praseodymium mainly consider either simple tungstates of the scheelite type CaWO 4 , − or tungstates with a double cation part of the MLn­(WO 4 ) 2 type, − although there are also works devoted to the compounds from the systems of complex oxides, for example, Ba 2 CaWO 6 /Pr 3+ . Because of doping with praseodymium atoms there are well-defined peaks in the emission spectra of the compounds.…”

“…The peaks appear in a wide range both in the visible and in the ultraviolet and infrared areas. This circumstance makes praseodymium-based compounds important laser and optical materials. , The luminescence intensity depends on the praseodymium content in a variable manner, for example, in the case of x Pr 3+ /NaGd­(WO 4 ) 2 reaches a maximum at a concentration of about 3.5 mol % Pr …”
