BluGlass Ltd of Sydney, Australia says it has succeeded in producing what it claims is the world’s first blue light emission from the uniform deposition of gallium nitride on a 6-inch diameter coated glass wafer.

The company is also developing a remote plasma CVD process for low-temperature deposition of GaN.
