Florida State University materials researchers has developed a new type of LED, using an organic-inorganic hybrid, organometal halide perovskites, that could lead to cheaper, brighter and mass produced lights and displays in the future. Perovskites are any materials with the same type of crystal structure as calcium titanium oxide.

After months of experiments using synthetic chemistry to fine-tune the material properties and device engineering to control the device architectures, they ultimately created an LED that performed even better than expected. The material glowed exceptionally bright...
