Descripción general

Cesium chloride is a highly water soluble crystalline solid withhigh refractive index and dielectric properties. It is widely used in the fieldof solid oxide fuel cells and lighting devices. [1] [2]

Aplicación

Cesium chloride can be used:
  • As crystal seeds to enhance the coverage of the CH3NH3PbI3−xClx absorber layer in perovskite solar cells. It helps to boost the power conversion efficiency of solar cells.[1]
  • As a medium to synthesize N and P-codoped carbon nanospheres for application in fuel cells and zinc-air batteries.[3]
  • To fabricate silicon nanopillars for solar cells, batteries, light-emitting diodes, etc.[4]
  • To enhance the thermal stability of polyoxometalates(used as electrode materials for lithium-ion batteries).[2]
  • To synthesize the lead-free halide double perovskite Cs2AgInCl6 with excellent moisture, light, and heat resistance. This material shows great potential for various optoelectronic applications, including photovoltaics.[5]

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
