| 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 |
