A method for preparing a laminate substrate for a light emitting device, includes (a) providing a glass substrate having a refraction index of between 1.45 and 1.65, (b) coating a metal oxide layer onto one side of the glass substrate, (c) coating a glass frit having a refractive index of at least 1.7 onto the metal oxide layer, the glass frit including at least 30 weight % of BiO, (d) firing the thus coated glass substrate at a temperature comprised between 530&#xb0; C. and 620&#xb0; C. thereby making react the metal oxide with the melting glass frit and forming a high index enamel layer with a plurality of spherical voids embedded in the lower section of the enamel layer near the interface with the glass substrate.
