Singapore Researchers Revolutionize Optical Dynamics with New Strategy
Singapore, Friday, 6 June 2025.
A Singapore team has developed pumping-flux modulation, achieving over tenfold changes in luminescence lifetimes, advancing optical encryption and flexible electronics innovation.
Innovative Breakthrough in Nanophotonics
On June 5, 2025, researchers at the National University of Singapore, in conjunction with the Institute of Materials Research and Engineering, have announced a groundbreaking technique in the field of nanophotonics. This new method, known as pumping-flux modulation, allows for reversible tuning of lanthanide optical luminescence, achieving more than a tenfold variation in luminescence lifetimes. This technology significantly advances nanophotonic applications by shifting control from complex material modifications to direct excitation management, enhancing real-time adaptability [1].
Implications for Optical Encryption and Flexible Electronics
The innovative method could pave the way for substantial improvements in optical encryption and flexible electronics. By achieving a tunable transition from green to near-infrared emissions through simple adjustments in excitation pulse duration and intensity, this development highlights potential use cases in secure optical communications and developing more responsive electronic displays [1]. Furthermore, the insight into dynamically programmable lifetime mapping can propel advancements in time-domain optical security, providing heightened security features for encrypted information [1].
Key Contributors and Global Impact
Central to this breakthrough is Xiaogang Liu, from the National University of Singapore, who spearheaded the development of the pumping-flux modulation strategy. Collaborations with Tianrui Zhai from Beijing University of Technology and Liangliang Liang from Xiamen University underscore the international dimension of this research effort [1]. This strategic approach is anticipated to inspire subsequent innovations in device design and material science, particularly in creating adaptable electronic devices that align with global trends towards interconnected and sustainable technologies [1][2].
Future Prospects in the Flexible Electronics Market
The flexible electronics market, valued at $30.11 billion in 2024, is projected to expand to $80.20 billion by 2033, with a robust annual growth rate of 11.50% from 2025 to 2033. Advances like the Singapore-led pumping-flux modulation strategy are poised to play a crucial role in this growth trajectory. The introduction of this adaptable technology could significantly reduce production costs and lead times for flexible OLED and AMOLED panels, which are in high demand for foldable smartphones, automotive displays, and medical devices [2].
