Dow Electronic Materials, a subsidiary of Dow Chemical, has completed its acquisition of Lightscape Materials.
The acquisition enables Dow to add Lightscape's specialty phosphor technology to its existing light-emitting diode (LED) technologies portfolio.
Leo Linehan, Dow Electronic Materials growth technologies business global general manager, said phosphor compositions help to improve quality, reliability and output colour of LED light-based systems.
"We look forward to helping customers incorporate these advanced phosphors into their processes, while providing the local service, support and supply they have come to expect from Dow."
"We are equally pleased to have the expertise of Lightscape co-founders Gerard Frederickson and Yongchi Tian as part of our LED technologies team."
Lightscape Materials' investors include Wisepower, a Korean company, and a US-based company, SRI International.
In October 2011, Dow formed a new LED technologies business segment to meet current and future demand for LEDs.
In addition to the new phosphor materials, Dow's products include metal-organic CVD precursors which are used to make the active light-emitting areas in LEDs, photoresists, related ancillaries for lithographic processing, metallisation processes for electroplating and pads and slurries for CMP.
Phosphors are used in LED lighting applications, such as in backlights for LCD displays and in residential, workplace and retail illumination.
