Flexible Amine Based Selenium Dissolution Free From Contaminants

A flexible, cost-effective, and contamination-free method for creating pure selenium solutions under a highly reducing atmosphere supports advanced manufacturing for electronics and solar cell applications.
Technology No. 2014-AGRA-66627

Selenide nanoparticles are important materials with applications in electronics, solar cells, light emitting diodes (LEDs), and biology. Making selenide particles first starts with the dissolution of elemental selenium with a reaction solvent. Current methods for making dissolved selenium, such as using organo-phosphine compounds or sodium borohydrine, are costly, unstable, and lead to contaminated, impure selenium solutions.

Researchers at Purdue University have developed a new method to control the dissolution of elemental selenium into a pure selenium solution. This method involves making a highly reducing atmosphere, which then solvates the selenium. The resulting reaction can be controlled and tuned to produce a range of desired solutions. This also provides opportunities to conduct additional chemical reactions with a pure selenium solution and create mixed chalcogen materials.

Advantages:

-Free of contaminants and impurities

-Flexible and controllable

-More stable and less costly

Potential Applications:

-Electronics

-Solar cells

-LEDs
