Research on Different Physical Property Characterization Approaches for OLED Materials

Abstract

Organic light-emitting diode, which is also commonly known as OLED, is one of the advanced materials for the development of the modern display technology. In the past decade, it has been well developed and successfully applied in display, lighting, screen devices and other fields. Before formally releasing them in the market, OLED materials need to be comprehensive tests on their performance to determine all parameters, of which their physical properties are of great importance to be included. In this paper, to systematically investigate on physical properties of OLED material, different approaches have been studied, including electroluminescence spectroscopy (ELS), photoluminescence spectroscopy (PL), time-correlated single-photon counting (TCSPC), and other approaches. At same time, this study also provides detailed information of each method of these characterizations for OLED materials. Through these analyses, the optical as well as electrical properties of these materials are well-studied. Overall, this research aims to gain a deeper understanding of OLED materials, which not only contributes to its future development, but also paves an avenue for the new generation of materials with advanced functions.
