Abstract

Room temperature phosphorescence phenomena of tens of commercailly available organic reagents and some guest/host system fabricated from certain reagents were investigated. Detailed luminescent properties and in-depth mechanism studies were carried out using a model system by photoluminescence, mechanoluminescence and ultrafast spectroscopy.
