Strong Photoluminescence and Versatile Functionalization

Molybdenum Disulfide Quantum Dots emit vibrant blue to green light due to their high quantum yield and have exceptional photostability under ambient conditions. Their surfaces can be functionalized with various chemical groups, such as carboxyl and hydroxyl, allowing compatibility with a wide range of applications and enhancing their selectivity for biomedical or sensing uses.

Excellent Dispersibility and Shelf Life

Offered as aqueous dispersions or powders, these dots are highly dispersible in water and polar solvents, ensuring uniform performance. Proper storage in cool, dry conditions with tightly sealed packaging ensures a shelf life of up to two years, maintaining their structural integrity and fluorescence properties.

Applications in Advanced Technologies

MoS Quantum Dots are tailored for diverse sectors, including biomedical imaging, optoelectronic devices, and catalytic systems. Their high purity, tunable emission, and nanomaterial grade make them ideal for laboratory research, industrial development, and innovative scientific exploration, particularly where nanoscale properties are critical.

FAQs of Molybdenum Disulfide Quantum Dots:

Q: How are Molybdenum Disulfide Quantum Dots typically stored to maintain quality?

A: For optimal shelf life and performance, these quantum dots should be stored in a cool, dry place with their container tightly sealed. Under proper conditions, they remain stable for 12 years.

Q: What is the benefit of surface functionalization for these quantum dots?

A: Surface functionalization with groups like carboxyl or hydroxyl allows the quantum dots to be tailored for specific applications, such as enhanced targeting in biomedical imaging or improved sensitivity in sensing devices.

Q: What process is used for dispersing MoS Quantum Dots in solvents?

A: Thanks to their inherent water solubility and hydrophilic surfaces, MoS Quantum Dots disperse easily in water and most polar solvents. Gentle sonication or stirring is sufficient to achieve a uniform dispersion for most applications.

Q: When is the strong blue to green photoluminescence best observed?

A: The intense photoluminescence of these quantum dots is most commonly observed under UV light, which excites the dots and causes them to emit in the blue to green range, suitable for imaging and detection tasks.

Q: Where can Molybdenum Disulfide Quantum Dots be applied effectively?

A: These quantum dots are widely used in biomedical imaging, chemical and biological sensing, optoelectronic devices, and as catalysts in various laboratory, research, and industrial settings due to their unique optical and chemical properties.

Q: What makes these quantum dots non-toxic at research levels?

A: MoS Quantum Dots are classified as non-toxic for research purposes, making them suitable for laboratory and biomedical applications involving cellular studies and imaging, provided standard handling protocols are followed.
