Ultralong Room Temperature Phosphorescence from Purely Organic Cluster Excitons

16 July 2019, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

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.
