Eu(2+) luminescence in strontium aluminates.
The luminescence properties of Eu(2+) doped strontium aluminates are reported and reviewed for a variety of aluminates, viz. SrAl12O19, SrAl4O7, Sr4Al14O25, SrAl2O4 and Sr3Al2O6. The aim of the research is to investigate the role of local coordination and covalency of the aluminate host lattice, related to the Sr/Al ratio, on the optical properties of the Eu(2+) ion. The UV and VUV excited lumi...
متن کاملSynthesis, Structure and Bonding in Triorganogermyl-alanes and Triphenylgermyl-aluminates
Triphenylgermyl-lithium in diethyl ether/THF did not react with Al2Me6 to form [(Ph3Ge)AlMe3]Li(THF)n. Addition of TMEDA to this solution yielded crystalline Ph3GeLi(THF)TMEDA. The reaction of Ph3GeLi in diethyl ether/hexane solution with H3Al-NMe3 in diethyl ether/THF generated [Ph3GeAlH3]Li(THF)4 while the reaction with Me2AlCl led to Ph3GeAlMe2(OEt2) and the trigermyl-aluminate [(Ph3Ge)3AlMe...
متن کاملRevised Thermodynamic Properties of Ca Aluminates: Implications for the Condensation
Introduction: The Ca-aluminates such as hibonite, CaAl 12 O 19 , grossite, CaAl 4 O 7 , and dmitryivanovite, CaAl 2 O 4 , belong to a suite of the most refractory minerals that could condense from a solar or fractionated nebular gas. While dmitryivanovite is a rather rear mineral found so far only in a few CAIs from the CH chondrites [1,2], both hibonite and grossite are fairly common [3] being...
متن کاملHeterometallic aluminates: alkali metals trapped by an aluminium aryloxide claw.
A series of heterometallic aluminium-alkali metal species [AlMMe2{2,6-(MeO)2C6H3O}2]n have been isolated for lithium, sodium and potassium. These compounds can be generated by the reaction of [AlMe2{2,6-(MeO)2C6H3O}]2 with the metallated phenol [M{2,6-(MeO)2C6H3O}]n or through the reaction of the mixture of AlMe3 and the appropriate alkali metal alkyl base with two equivalents of 2,6-dimethoxyp...
متن کاملSynthesis and Characterization of Precursors for Group II Metal Aluminates
Precursors to Group II metal aluminates (MAI2O4 , M=Mg, Ca, Ba, Sr) are synthesized from inexpensive starting materials including Group II metal oxides/hydroxides, Al(OH)3 , triethanolamine (TEA) and ethylene glycol, in a one-pot synthesis process. The precursors are soluble in common organic solvents and can be handled in moist air for a reasonable period of time. On pyrolysis in air to 1200 °...
