“…The reasons for blue and green PL emissions of BaWO 4 are discussed in many different aspects ranging from defect centers by interstitial oxygen atoms to structural disorder in the crystal lattice [8][9][10][11]. BaWO 4 also serves as a potential material for designing all solid-state lasers, especially that it has been considered as a unique Raman crystal for a wide variety of pump pulse durations in Raman laser pulses [12][13][14][15][16][17]. Its other applications include nuclear spin optical hole burning hosts [6], radiation detection [1], scintillating devices [4], and other electro-optic applications [1].…”

Synthesis of nano-BaWO4by a modified combustion technique and its suitability for various applications are reported. The structure and phase purity of the sample analyzed by X-ray diffraction, Fourier transform Raman, and infrared spectroscopy show that the sample is phase pure with tetragonal structure. The particle size from the transmission electron microscopy is 22 nm. The basic optical properties and optical constants of the nano BaWO4are studied using UV-visible absorption spectroscopy which showed that the material is a wide band gap semiconductor with band gap of 4.1 eV. The sample shows poor transmittance in ultraviolet region while maximum in visible-near infrared regions. The photoluminescence spectra show intense emission in blue region. The sample is sintered at low temperature of 810°C, without any sintering aid. Surface morphology of the sample is analyzed by scanning electron microscopy. The dielectric constant and loss factor measured at 5 MHz are 9 and1.56×10-3. The temperature coefficient of dielectric constant is −22 ppm/°C. The experimental results obtained in the present work claim the potential use of nano BaWO4as UV filters, transparent films for window layers on solar cells, antireflection coatings, scintillators, detectors, and for LTCC applications.

The Role of Short-Range Disorder in BaWO₄ Crystals in the Intense Green Photoluminescence

et al. 2011

An intense and broad visible photoluminescence (PL) band was observed at room temperature in short-range disordered BaWO 4 crystals. The scheelite crystalline BaWO 4 powders prepared by the polymeric precursor method and annealed at different temperatures were structurally characterized by means of X-ray diffraction and Fourier transform (FT) Raman spectroscopy measurements. Quantum-mechanical calculations indicated that the disorder at short range only of Ba atoms in the BaWO 4 lattice has a very important role in the charge transfer involved in the intense green PL emission. This indication was detected and confirmed by means of FT Raman spectroscopy measurements. The experimental and theoretical results are in good agreement, both showing the specific type of structural disorder that is the most favorable condition for generating the most intense green PL emission in the scheelite BaWO 4 lattice.

The parameters g-factor (g|| and g⊥) together with the local structure of the Ce3+ center in BaWO4 single crystal (scheelite structure crystals) were theoretically investigated using a complete diagonalization procedure of energy matrix (CDM method). The intrinsic parameters were calculated. It is shown that the experimental and the calculated values of the g-factors are in good agreement. The angular distortion has also been calculated. It was found that the polar angles of the impurity–ligand bonding are smaller than in BaWO4 single crystal (Δθ≈1.00 ) . The validity of the results and the changing in the local environment of the impurity–cerium ion is also discussed.
