Definitions
- an advantageous embodiment of the invention provides that the nanomaterials are formed by clusters embedded in a matrix, which are preferably surrounded by organic ligand shells. It is advantageously possible here to stabilize the clusters via the ligand shells and thus to make the hole-injecting electrode and / or the electron-injecting electrode corrosion-resistant.
- the electron work function of the respective electrode can be adjusted via the dimensioning of the clusters.
- FIG. 2 is a schematic sectional view through an electroluminescent system according to another embodiment. Description of the embodiments
- Electrodes 14 and 16 can also be arranged between the electrodes 14 and 16, these also for light emission or one Charge carrier transport to the light-emitting material 12 are used.
