A green emissive amorphous fac-Alq3 solid generated by grinding crystalline blue fac-Alq3 powder

A novel green emissive Alq3 solid with a facial isomeric form has been obtained by grinding the typical blue luminescent fac-Alq3 crystalline powder. This is the first report, to the best of our knowledge, that a fac-Alq3 isomer emits green light.
