ORGANIC LUMINESCENT MATERIAL EXHIBITING ROOM TEMPERATURE PHOSPHORESCENCE AND OPTICAL DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel luminescent material capable of being synthesized at inexpensive price, having excellent optical properties including strength of light emission intensity, large Stokes shift and long term stability of light emission intensity, and excellent in high heat resistance (5% weight reduction temperature:330°C or more), chemical stability and film making property.;SOLUTION: There is provide a luminescent material exhibiting phosphorescent at wavelength of 500 to 800 nm at a temperature around room temperature and containing polyimide having an acid dihydrate part having boron, iodine or the like in a repeating unit (following formula is example). There is provided a luminescent material usable as a temperature sensor or an oxygen sensor.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
