The 19th Asian Games, held from Sept. 23 to Oct 8 in Hangzhou and five other cities in Zhejiang,     1     (come) to an end recently. It is undoubtedly the most     2     (amaze) sporting event of the year, with 15 world records broken. The competitive atmosphere and sportsmanship displayed by athletes are impressive. Besides,     3     makes it more spectacular is that “Green Games” has become a calling card for it. Green energy sources were used at all 56 competition venues. For example, digital technologies were used for managing carbon emissions from venues in the six cities     4     the Games were held.

7 . “Roses are red. Violets are blue.” As an English poem tells us, most things we see in the world have a certain color. However, if a red rose shrinks (缩小) to the world of nanometers (纳米), chances are you might see it in orange, yellow, or blue, depending on its size. This incredible phenomenon is due to the quantum effect (量子效应).

An element’s properties (性质) are largely determined by how many electrons it has, noted the Royal Swedish Academy of Sciences. However, when matter shrinks to nanometers, its properties are determined by its size. Based on this effect, Alexei Ekimov from Russia and Louis Brus and Moungi Bawendi from the US received the Nobel Prize in chemistry this year for the discovery and development of quantum dots (量子点), semiconducting nanoparticles (半导体纳米粒子) that are usually 2 to 10 nanometers in size.

“Quantum dots have many fascinating and unusual properties. Importantly, they have different colors depending on their size,” said Johan Aqvist, Chair of the Nobel Committee for Chemistry.

Quanturn dots absorb light and then release it at another wavelength (波长). The smaller the dot is, the shorter the wavelength is, resulting in a bluer light. Likewise, the larger it is, the redder the light will be.

The research by the three scientists opened up a whole new world for chemistry. The light from quantum dots is pure and bright, providing more convenience and enjoyment in many aspects of our lives.

In hospitals, quantum dots are applied to bioimaging (生物成像) and traceable (可追踪的) drug delivery. They can guide doctors when they remove tumors (肿瘤). The dots are much brighter than traditional organic dyes (染料). In our homes, we enjoy pure and dynamic light from TV and computer displays using QLED technology (Q stands for quantum dots). In labs, chemists make use of light from quantum dots to catalyze (催化) chemical reactions.

Looking ahead, scientists believe that quantum dots could help in the making of tiny sensors and thinner solar cells. , as well as in encrypted (加密的) quantum communication. Quantum dots have been benefiting humankind in many ways. However, our exploration of them is still at an early stage.
