Self-trapped Exciton Luminescence and Light-emitting-diodes Based on Zero-dimensional Organic-inorganic Hybrid Antimony Chloride增强出版
The emerging of the zero-dimensional metal halide materials has attracted great attention of researchers due to their excellent photoelectric properties. Herein

respectively. The optoelectronic properties of [(C

can emit bright orange-red emission under the ultraviolet excitation. This orange-red emission originates from the triplet self-trapped exciton induced by the zero-dimensional spatial confinement. Temperature dependent PL and decay lifetime studies reveal that the material has a thermal activation energy with the value of ~600 meV
thus it has favorable anti-thermal quenching effect. By optimizing the device structure and introducing poly [bis(4-phenyl)(4-butylphenyl)amine] (Poly-TPD) as a hole transport layer
the warm white emission by mixing the fluorescence emission of Poly-TPD and the self-trapped exciton emission of [(C

under a bias of 6 V. This work provides an alternative approach for the development of the manufacture of lead-free metal halide electroluminescent devices by solution method.
