BEACON TRANSCRIPT – A team of KAUST scientists has recently unveiled a new material, a type of perovskites which can reportedly change its shape as it comes into contact with light. This revolutionary “crystalline material” is based on perovskite crystals which are already recognized for their ability to harvest sunshine power.
New Material to be the Base Behind New Light-Controlled Appliances?
The team of scientists behind this invention comes from KAUST or the King Abdullah University of Science and Technology based in Saudi Arabia.
Perovskites crystals had been recognized earlier for their capabilities of harvesting power from the sun. But the research team looked to determine if these abilities could go even further. For this, they took a closer look at the photostriction of a perovskite termed MAPbBr3 and its capabilities.
To do this, the team made use of Raman spectroscopy. This can analyze the atomic vibrations from the formation. Jr-Hau He, who is a KAUST electrical engineer and the lead researcher, pointed out that MAPbBr3 was proven to have ‘extreme’ and ‘vigorous’ photostriction activities.
By using the Raman spectroscopy, the researchers also confirmed that this crystalline material would be capable of changing its shape in response to sunlight.
“During the investigation, we found out that, in situ Raman spectroscopy with confocal microscopy is one of the most reliable classification tools for expediently assessing inherent photo-induced lattice deformation,” states the team.
The scientists then continued by presenting their plan of using the same approach in measuring the photostriction abilities of other materials as well.
According to their statement, the team will also be looking to “draw on this new material”. They consider that it could come to be used in the fabrication of “next-generation optoelectronic machines”. Or perhaps of counting wireless remote switchable devices and several other light-controlled appliances.
Current study results are now available in a paper in the journal Advanced Materials.
