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
The commonly used method is to disperse the rare earth compound as a dopant into the transition metal coordination polymer and physically mix it. Due to the poor dispersion of the rare earth complex in the polymer matrix, it is easy to separate from the matrix and other shortcomings, resulting in doping The stability of the material is poor, the concentration quenching occurs between the fluorescent molecules, and the fluorescence intensity decreases
