General description

Aluminum isopropoxideis a metal-organic compound that consists of an aluminum atom bonded with threeisopropoxide ligands. It is used as a precursor for the synthesis of high-surfacearea alumina and other aluminum-containing materials. In addition, it is usedto prepare metalorganic chemical precursors for the growth of thinfilms and coatings.

Application

Aluminum isopropoxide can be used as:
  • Sol-gel precursor to synthesize ZnAl2O4 powders for transparent ceramics.
  • Precursor material for the fabrication of nanosized SAPO-34 zeolites with a 4-fold increase in catalytic lifetime and significantly increased selectivity.
  • A starting material to prepare long-persistent luminescence materials for display devices and bioimaging.
  • Coating material to fabricate electrodes for lithium-ion batteries to enhance cycling stability and performance.
  • A catalyst for alkylation of resorcinol with camphene.

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
