Optical Properties and Microdefects in CaMoO4 Single Crystals

Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation

“…In particular, molybdates phosphors were implemented in optical applications [10][11] and evaluated extensively over the past century as a scintillating medium and electro-optical devices, given their broad and intense absorption bands due to the charge transfer (CT) from oxygen to the metal in the near-ultraviolet (UV) region [12][13][14][15][16] . Among molybdates, CaMoO4 is considered an outstanding matrix material for the synthesis of highly applicable luminescent materials due to its excellent physical and chemical properties [17][18][19][20][21][22][23][24] . Moreover, CaMoO4 exhibits a tetragonal structure and space group I41/a 25 with a shared edge 27 .…”

“…Alkali-earth molybdates MMoO 4 (M = Ca, Sr, Ba) include a wide range of scientifically and technologically significant compounds. These materials are chemically designed and further synthesized using different methods based on the final objective. − In particular, molybdates phosphors were implemented in optical applications , and evaluated extensively over the past century as a scintillating medium and electro-optical devices, given their broad and intense absorption bands due to the charge transfer (CT) from oxygen to the metal in the near-ultraviolet (UV) region. − Among molybdates, CaMoO 4 is considered an outstanding matrix material for the synthesis of highly applicable luminescent materials due to its excellent physical and chemical properties. − Moreover, CaMoO 4 exhibits a tetragonal structure and space group I 4 1 / a . In the scheelite structure, the Mo cations are bonded to four oxygens, which form the tetrahedral [MoO 4 ] clusters; whereas the Ca cations are coordinated to eight oxygen anions, which form the dodecahedron [CaO 8 ] clusters , and can be described as a layered arrangement composed of noninterconnected [MoO 4 ] and [CaO 8 ] clusters that form chains parallel to [11̅0] with a shared edge .…”

Анизотропия упругих и фотоупругих свойств кристаллов CaМоО4

“…Как известно, кристаллы молибдата кальция и твердые растворы на их основе могут использоваться в качестве активной среды в лазерной технике, криогенных фононных сцинтилляционных детекторах, а также в акустооптичесих устройствах [3]. В настоящей работе изучены упругие и фотоупругие свойства кристаллов CaΜoO 4 (точечная группа симметрии 4/m), которым посвящен ряд работ [4][5][6] ( 1) ( 1)…”

Facile synthesis of ZnMoO4/AlPO4-5 nanorod composites as visible-light-driven photocatalysts and high-performance energy storage materials

“… 12,13 The photoactivity of ZnMoO 4 is a result of its structural diversity, superior optical properties in a broad emission spectrum, and substantial charge transfer between the bands of activated 2p (O 2 ) and 4d (Mo 6+ ) orbitals. 14 In addition, possible improvements to the photocatalytic capabilities of traditional inorganic semiconductors could include their large specific surface area, broad visible-light absorption, and adjustable bandgap edges. 15 It has been demonstrated that loading and dispersing ZnMoO 4 particles on suitable supports is a viable alternative method for achieving the aforementioned goals.…”
