Gold nanorod plasmonic upconversion microlaser [PDF]
14th IEEE International Conference on Nanotechnology, 2013 Plasmonic-photonic interactions have stimulated significant interdisciplinary interest, leading to rapid innovations in solar design and biosensors. However, the development of an optically pumped plasmonic laser has failed to keep pace due to the difficulty of integrating a plasmonic gain material with a suitable pump source.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Avalanche upconversion in Tm:YALO_3 [PDF]
Optics Letters, 1991 We report the sudden appearance of upconversion fluorescence and resonant increasing absorption above a threshold intensity in Tm YALO3 at room temperature. These effects are shown to arise from nonlinear, cooperative, excited-state dynamics. Comparison with quantum theory reveals essential roles both for pairwise cross relaxation and excitation ...

Space Group Modulated Upconversion and Mechanoluminescence in [YbEu] Cocrystal Complexes
Advanced Optical Materials, EarlyView.We report here a space group regulation strategy to optimize both upconversion and mechanoluminescence in cocrystal assemblies, representing the first example of integrating these two properties within a single lanthanide complex material. ABSTRACT Lanthanide complexes exhibiting stimuli‐responsive luminescence, such as upconversion (UC) and ...
