Fuji Pigment Co., Ltd. has Established a Large-Scale Manufacturing Process for Silicon Quantum DotsKAWANISHI, Japan, May 25, 2017 /PRNewswire/ -- Quantum dots are extremely tiny man-made nanoparticles typically between 10 to 10000 atoms (1 to 10 nanometers) in diameter, which is smaller than 1/10000 th the width of a human hair. However, the effects of this extreme small size cannot be ignored. Quantum dots are actually very powerful materials, and it is their size that gives them unique abilities, including converting light to nearly any color in the visible spectrum with very high efficiency. The electronic characteristics of quantum dots are determined by quantum confinement effect depending on their chemical composition, size, and shape. This means that we can control the color of light given off by a quantum dot just by changing its size. Bigger dots emit longer wavelengths, such as red, while smaller dots emit shorter wavelengths, such as green or blue. The tune of a quantum dot is the wavelength of light that it emits. This unique properties of quantum dot can be utilized for following application.
In this regard, Dr. Ryohei Mori at Fuji Pigment Co., Ltd (Kawanishi city, Japan) has been diligently researching and developing inexpensive quantum dots based on safe materials, and has succeeded in developing a large-scale manufacturing process for silicon quantum dots. Dr. Ryohei Mori has been already established the large scale production process for carbon quantum dot and graphene quantum dot which are also environmentally friendly materials. However, with silicon quantum dots, on top of its no toxicity, light to electricity conversion efficiency enhancement can be expected with solar cell. Silicon quantum dots exhibits visible and infrared emission light simultaneously which is also very unique property. Quantum yield exceeds 30 % (Dr. Ryohei Mori is still pursuing higher quantum efficiency).
