Title: LOW MELTING GLASS FOR PROTECTING OXYGEN SENSITIVE ORGANICS
Abstract:
An optically transparent mixture comprising an organic luminescent reference material, and a low melting glass composition. This can be used as an attractive component in optical CO2 sensors, since the protection of the organic material against oxygen when embedded in the low melting class serves to provide a long life time for such organic luminescent reference material. Especially, the low melting glass composition may comprise TinPhosphate glass, and the organic luminescent reference material may comprise [Ru(bpy)3]Cl2.
