Chan, Kok Ken, 2022, "Replication Data for: Water-stable Perovskite Quantum Dots-Based FRET Nanosensor for the Detection of Rhodamine 6G in Water, Food, and Biological Samples",, DR-NTU (Data), V1, UNF:6:DBhvRwxxlwI1iwvRkAnN1A== [fileUNF]
The practical application of perovskite quantum dots (QDs) for sensing in the aqueous phase has been restricted by their poor resistance to moisture and oxygen due to their highly ionic characteristic. In this work, we employed silica and phospholipid co-encapsulated water-stable...

Ramesh, Sankaran, 2022, "Replication Data for: Tailoring the Energy Manifold of Quasi-2D Perovskites for Efficient Carrier Extraction",, DR-NTU (Data), V1
Harvesting the excess energy from absorbed above bandgap photons is a promising approach to overcome the detailed balance limit for higher solar cell efficiencies. However, this remains very challenging for 2D layered halide perovskites as the fast excess energy loss competes eff...

Lim, Jia Wei Melvin, 2022, "Replication Data for: Spotlight on Hot Carriers in Halide Perovskite Luminescence",, DR-NTU (Data), V1
Harnessing hot carriers’ (HC) excess energy is an attractive approach to surpass the Shockley-Queisser limit. Halide perovskites possess desirable slow HC cooling properties for developing next-generation solar cells. Their HC cooling properties on the ultrafast timescale are wel...
