Abstract:
The development of high-performance luminescent materials is essential for advancing optoelectronic applications, particularly in the field of solid-state lighting and displays. This study investigates the structural, optical, and thermal properties of the 0D organic-inorganic hybrid metal halides (OIHMHs) (2,6-DTP)2ZnCl4·DMF and its Sb3+-doped derivatives, aiming to enhance the luminescent efficiency and stability for potential applications in white light-emitting diodes (WLEDs). The Sb3+-doped (2,6-DTP)2ZnCl4·DMF samples showed broad emission spectra covering the entire visible region, with distinct peaks at 505 and 647 nm with the photoluminescence quantum yield (PLQY) of 91.9% and high thermal stability. Furthermore, the (2,6-DTP)2ZnCl4·DMF-based WLEDs exhibited stable white light emission with a high color rendering index (CRI) of 91 and a correlated color temperature (CCT) of 5635 K. This research provides valuable insights into the design and optimization of efficient luminescent materials for optoelectronic applications, contributing to the development of next-generation lighting technologies.
