Problems solved by technology

However, the preparation process of doped devices is complex and costly, and the phase separation phenomenon often occurs in host-guest devices, which reduces the device efficiency, and the wavelength of the material is almost limited, so it is difficult to modify according to needs
Also due to the poor thermal stability of conjugated organic polymer polymer materials, concentration quenching occurs between fluorescent molecules, and the fluorescence lifetime decreases.
