Abstract
Glass frit compositions, calculated in mole percent on an oxide basis, consisting essentially of 24.5 to 29.0% P O ; 1.0 to 5.0% B O ; 1.0 to 2.0% Al O ; and sufficient amounts of SnO and ZnO (51.5 to 66.5% SnO, and 5.0-12.0% ZnO), wherein the molar ratio of SnO:ZnO is in the range of about 5.0:1 to 12:1, and 0.0 to 2.0% SiO . The glass compositions exhibit, under NMR spectroscopic analysis of B nuclei, a signal containing at least two peaks at a chemical shift in the range of approximately −18 to −25 ppm. The frit compositions exhibit long term stability, durability, and resistance to attack against moisture in high temperature and humidity conditions and are capable of attaching optical fiber Bragg gratings without the use of a hermetic chamber and the like. An optoelectronic device that employs a sealing material that comprises a frit made from the glass compositions.
