Process for producing a layer composite consisting of a luminescence conversion layer and a scattering layer |
| 摘要 |
A process of producing a layer composite includes a luminescence conversion layer and a scattering layer, wherein a press having a first pressing tool with a cavity and a second pressing tool is used including introducing a first polymer including a luminescence conversion substance into the cavity, inserting a film between the first and second tools, closing the press and carrying out a first pressing, hardening the first polymer to form a luminescence conversion layer in the press, opening the press, wherein the luminescence conversion layer adhering to the film remains in the press, introducing a second polymer including scattering particles into the cavity, closing the press and carrying out a second pressing, hardening the second polymer to form a scattering layer disposed on the luminescence conversion layer, opening the press, and removing the support film with the layer composite including the luminescence conversion layer and the scattering layer. |

1. A process of producing a layer composite comprising a luminescence conversion layer and a scattering layer, in which a molding press having a first pressing tool with a cavity and a second pressing tool is used, comprising:
introducing a first polymer comprising a luminescence conversion substance into the cavity, inserting a support film between the first and the second pressing tool, closing the molding press and carrying out a first pressing procedure, hardening the first polymer to form a luminescence conversion layer in the molding press, opening the molding press, wherein the luminescence conversion layer adhering to the support film remains in the molding press, introducing a second polymer comprising scattering particles into the cavity, closing the molding press and carrying out a second pressing procedure, hardening the second polymer to form a scattering layer disposed on the luminescence conversion layer in the molding press, opening the molding press, and removing the support film with the layer composite comprising the luminescence conversion layer and the scattering layer.
