Enhanced Anti-thermal Quenching of 3,8-Dibromo-1,10-phenanthroline-Based MOFs for Phosphor-Converted LED

Hui-Lin Wang, Mi Li, Chang Zhong-fang, J. -F. Liu et al.

Short summary

Two novel MOFs based on 3,8-dibromophenanthroline exhibit distinct anti-thermal-quenching properties, with the Cd-MOF showing only 11.9% luminescence loss at 150°C, outperforming many inorganic phosphors.

Abstract

Abstract Diverse coordination geometries of Zn(II) and Cd(II) give rise to distinct halogen bonding interactions and spatial arrangement of the 3,8-dibromophenanthroline luminescent center in two MOFs. The two materials exhibit distinct thermal quenching degrees of 38.9% and 11.9% at 150 °C. The Cd-MOF presents outstanding anti-thermal-quenching performance superior to many reported inorganic phosphors. Assembled phosphor-converted LED devices confirm their great potential for solid-state lighting.
