Phosphorescence emission from BAlq by forced intersystem crossing in a colloidal photonic crystal

Bis(2-methyl-8-quinolinato)-4-phenylphenolate aluminium (BAlq) does not show phosphorescence. Only in the presence of an emitting sensitiser and at low temperature, phosphorescent emission has been reported from this molecule. We report for the first time, up to our knowledge, phosphorescent emissio...

Summary:Bis(2-methyl-8-quinolinato)-4-phenylphenolate aluminium (BAlq) does not show phosphorescence. Only in the presence of an emitting sensitiser and at low temperature, phosphorescent emission has been reported from this molecule. We report for the first time, up to our knowledge, phosphorescent emission from BAlq at room temperature in the absence of sensitisers by trapping the molecule in a photonic crystal (PhC). BAlq has been embedded first in a polymer matrix and subsequently inserted within a colloidal PhC in order to create the optical confinement that suppresses the available energy modes for fluorescence and favours intersystem crossing, giving rise to the unusual triplet emission.
