Growth of CaWO4 whiskers from KCl flux

Luminescence investigation of red phosphors Ca0.54Sr0.34−1.5xEu0.08Smx(MoO4)y (WO4)1−y for UV-white LED device

“…To solve this problem, both methods need efficient red phosphors having the excitation wavelength matching with the emission wavelength of the blue LEDs (l em ¼ 440-470 nm) or the UV-LEDs (l em ¼ 350-410 nm). Currently, some sulfide phosphors such as (Ca, Sr)S:Eu 2+ [2] and Y 2 O 2 S:Eu 3+ [3] are commercially being employed as red phosphors and their efficiencies are not desirable. Hence it is necessary to seek alternative red phosphors with luminance and satisfactory chemical stability.…”

Microstructural and optical characterization of CaWO4 and SrWO4 thin films prepared by a chemical solution method

“…In recent years, crystal structures based on the scheelitetype have attracted much interest because of their approved use as scintillating medium and in electro-optic applications [1][2][3]. In addition, scheelite-type structure materials have been a subject of numerous investigations on the luminescent properties [4,5].…”

Nd induced changes in IR spectra of CaWO4 single crystals

“…CaWO 4 is an optical material, which has attracted particular interest because of its importance in applications as a laser host material [1] in quantum electronics or scintillators [2][3][4][5][6]. In addition, the scheelite-type structure materials have been a subject of numerous investigations on the luminescent properties [7,8].…”

“…Various methods such as the Czochralski technique [12,13], flux method [14,15] and solid-state reactions [16] have been used to synthesize single crystals, whiskers, and powders of CaWO 4 . In our previous paper [12,13], we obtained CaWO 4 and Nd:CaWO 4 single crystals using the Czochralski technique taking hydrodynamics equations into account, as we have successfully done for many oxide single crystals (Bi 12 SiO 20 [17], Bi 12 GeO 20 [18], sapphire [19], Nd:YAG [20], etc.).…”
