Quantum Dot Longevity: A Balancing Act
The Precarious Beauty: Unpacking the Stability and Degradation of Quantum Dots Quantum dots (QDs), those tiny semiconductor nanocrystals that can emit light in a rainbow of colors depending on their size, hold immense promise for technological advancements. From dazzling displays to powerful biomedical imaging, their unique properties are revolutionizing diverse fields. But beneath this shimmering allure lies a crucial challenge: maintaining their stability and preventing degradation over time. The stability of QDs hinges on several factors, primarily the protection of their surface from environmental influences. Imagine these tiny crystals as sparkling jewels, vulnerable to the harsh conditions of our world. Exposure to air, moisture, light, and even heat can cause detrimental changes, leading to a gradual loss of their luminescence...
