Abstract
The present invention is directed to a method for preparing a glass device comprising the steps of: —preparing a mixture comprising: —at least two glass components, —a solvent, —at least one binder system, —optionally at least one defoamer, —blending the mixture to form a blend mixture, —grinding the blend mixture to form a grinded mixture, —casting the grinded mixture to form a layer, and —drying the layer to form a dried layer of a glass device. The present invention is further directed to a glass device, a wavelength converter and a light emitting device comprising the glass device and/or the wavelength converter.

A glass device comprising:
- a matrix consisting essentially of at least one glass component and at least one glass particle intercalated in the matrix,
- wherein the glass component and the glass particle are independently selected from the group consisting of aluminosilicates, borosilicates, soda lime silicates, crown glasses, flint glasses, high silica glasses and low melting point solder glasses, and
- wherein the glass component of the matrix has a higher softening point than the glass particle intercalated in the matrix.
A wavelength converter comprising:
- a matrix consisting essentially of at least one glass component, at least one phosphor and at least one glass particle intercalated in the matrix,
- wherein the glass component and the glass particle are independently selected from the group consisting of aluminosilicates, borosilicates, soda lime silicates, crown glasses, flint glasses, high silica glasses and low melting point solder glasses, and
- wherein the glass component of the matrix has a higher softening point than the glass particle intercalated in the matrix.
