PVD preparation and spectral study of organic electroluminescent material 8-hydroxyquinoline lithium

Abstract

The usage of organic electroluminescent materials has increased due to their processing benefits and distinctive functional characteristics. In this study, physical vapor deposition (PVD) was used to create the spherical organic luminous material 8-hydroxyquinoline lithium (Liq) with high purity and excellent phase. The performance of the luminescence was evaluated. The luminous lifespan region was found to be more concentrated, and it was discovered that the emission spectra of the products created a redshift. Evidently, this phenomena lowers exciton diffusion and relaxation consumption, which is better for the materials device. Additionally, we investigated the Liq's luminescence characteristics in various solvents and examined the lifetime and phosphorescence spectrum, which laid the groundwork for the material's widespread use in a variety of settings and applications.
