White LEDs without glare

    Article metrics

    A new luminescent material reduces the glare of white light-emitting diodes (LEDs) and could make them more practical for home lighting.

    A team led by Hisayoshi Daicho of Koito Manufacturing in Shizuoka, Japan, designed the material, which consists of chlorosilicates that have been implanted with europium ions. The phosphor absorbs violet light and re-emits it in a yellow shade. The researchers combined this phosphor with a blue one and then added a violet LED to create a system that emits white light with a uniform hue (pictured) and no glare.
