With a remarkable portfolio of 6 patents, he has made strides in advancing technology that enhances luminous efficiency and color purity in lighting applications.

Latest Patents

Among his latest innovations, Hae-Jung Son has developed organometallic complexes and an organic electroluminescence device utilizing these complexes. One of his notable patents focuses on an organometallic complex that effectively increases the energy band gap between the Highest Occupied Molecular Orbital (HOMO) and triplet Metal-to-Ligand Charge Transfer (MLCT) states. This advancement allows for highly efficient phosphorescence and expands the potential applications in organic electroluminescent devices. The organometallic complex can form an organic layer that emits light in the wavelength range of 400-650 nm and can induce white electroluminescence when paired with green or red luminescent materials.

Another innovative patent by Son describes an organic electroluminescent device featuring a carefully constructed emission layer. This layer includes a host, phosphorescent emission molecules as dopants, and a fluorescence supporter that improves luminous efficiency. The design enables the fluorescence supporter to either receive energy from the host or trap energy directly, leading to enhanced light emission. The emission spectrum of the fluorescence supporter and the absorption spectrum of the phosphorescent emission molecule either partially or completely overlap. This pioneering system is particularly beneficial in the production of blue emission devices.
