Rice Husks can now be used to make LED lights



A team of scientists in Japan at the Natural Science Center for Basic Research and Development, Hiroshima University has made a breakthrough discovery that could see rice husks being used to make LED lights. By using the high purity silica content in rice husks together with the value added SI power, they are now able to convert them into the first silicon quantum dot. This exciting development could lead to a whole new way of producing LED lights and could help reduce the cost of this type of lighting.


Rice husks are the hard outer shells that encase the grain of rice. They are typically discarded after the rice is harvested, but the Japanese scientists have found a way to use them to create environmentally-friendly LED lights. The Japanese scientists used the high purity silica content in rice husks to create the first silicon quantum dot. Silicon quantum dots are tiny particles that emit light when excited by an electric current. The process of creating them is usually very expensive, but the Japanese scientists found a way to do it using rice husks, which are a waste.


The significance of their discovery

The discovery could lead to a whole new way of producing LED lights and could help reduce the cost of this type of lighting. LEDs are becoming increasingly popular because they use less energy than traditional light bulbs and last much longer. However, they can be quite expensive, so if the Japanese scientists’ method for making them from rice husks becomes.
