A new study led by Associate Professor Dong Zhaogang from the Singapore University of Technology and Design (SUTD) has found a way to achieve substantial wavelength tuning at ambient conditions using tiny, tunable nanostructures and low-voltage electrical control. This discovery is published in Advanced Materials in a paper titled, “Electrically tunable and modulated perovskite quantum emitters via surface-enhanced Landau damping”.

Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots – making the process faster, more energy-efficient and environmentally sustainable – without compromising material quality.

In a recent study, researchers from Chiba University delved into a promising path toward solid-state optical cooling using perovskite quantum dots. Focused on anti-Stokes photoluminescence, a process in which materials emit higher-energy photons than they absorb, this research could revolutionize the existing cooling technology. Their findings highlight both the potential and limitations of this novel cooling approach, with exciting prospects in energy-saving technology.
