LED lighting can provide huge energy savings but the high manufacturing costs of the technology has, so far, prevented it from being widely adopted. Now, Zhibin Yu — an engineering professor from Florida State University — has developed a low cost variation of the light-emitting diode, which could lead to greater uptake of the eco-friendly option. Yu's single-layer LED technology is a combination of organic and inorganic materials. It dissolves and is applied like paint as a thin film. It can then be sandwiched between indium tin oxide and indium-gallium eutectic, and used to make a lightbulb, which will shine…
