InP/ZnS Fluorescent Nanocrystals
Inquiry
Product Description
The wavelength range of our quantum dots is 530-650 nm, and 5 mg/mL is stable in toluene, meanwhile, you can also customize the quantum dots with corresponding wavelength, concentration and solvent according to your experimental or project requirements. InP/ZnS crystals have a large exciton wave radius compared to group II-VI crystals, a significant quantum limit field effect, a large extinction coefficient, and an emission spectrum covering the entire visible range and extending to the near-infrared region, especially without heavy metal elements.
Advantages of Our Products
Alfa Chemistry offers InP/ZnS fluorescent nanocrystals with good stability, wide range of fluorescence emission peaks, high luminescence efficiency, and adjustable wavelength.
Applications
InP/ZnS fluorescent crystals have a wide range of applications in addition to flat panel display backlighting, lighting, biomedical labeling and solar energy, as well as the following applications. You can choose our suitable products according to your needs.
ATP was detected by InP/ZnS nanocrystals
InP/ZnS quantum dots (QDs) were fluorescently detected on adenosine triphosphate (ATP). The effects of the enzymatic reactions of glucose oxidase (GOX) and hexokinase (HEX) on InP/ZnS quantum dots were spectroscopically analyzed at physiological pH. InP/ZnS quantum dots act as glucose sensors in the presence of GOX, Glu and ATP, and undergo fluorescence bursts during the release of hydrogen peroxide. However, in the presence of adenosine triphosphate, glucose and HEX, InP/ZnS quantum dots were recorded as significantly photo-brightened depending on the concentration of ATP in the sample. ATP was linearly related to the emission intensity of InP/ZnS nanocrystals.
