Abstract
The present invention provides an organic material that is characterized by including a rigid matrix and a dye having a phosphorescence lifetime of 0.1 seconds or more in a rigid medium at 77 K and that exhibits such a strong and long-lived phosphorescence as to be recognizable with the naked eyes even at ordinary temperature: namely, an ordinary-temperature-phosphorescent organic material.
