Tuning the circularly polarized photoluminescence of chiral 2D perovskites by high pressure
Shenyu Dai
Chiral 2D perovskites are of great interest as circularly polarized photoluminescence materials, but these materials generally exhibit weak CPL under ambient conditions. Several st…
Theory and Experiments of Pressure-Tunable Broadband Light Emission from Self-Trapped Excitons in Metal Halide Crystals
Shenyu Dai, Xinxin Xing, Viktor G. Hadjiev +9
Hydrostatic pressure has been commonly applied to tune broadband light emissions from self-trapped excitons (STE) in perovskites for producing white light and study of basic electr…
Photoacoustic Identification of Laser-induced Microbubbles as Light Scattering Centers for Optical Limiting in Liquid Suspension of Graphene Nanosheets
Qiuhui Zhang, Yi Qiu, Feng Lin +8
Liquid suspensions of carbon nanotubes, graphene and transition metal dichalcogenides have exhibited excellent performance in optical limiting. However, the underlying mechanism ha…
Self-formed 2D/3D Heterostructure on the Edge of 2D Ruddlesden-Popper Hybrid Perovskites Responsible for Intriguing Optoelectronic Properties and Higher Cell Efficiency
Zhaojun Qin, Shenyu Dai, Chalapathi Charan Gajjala +15
The observation of low energy edge photoluminescence and its beneficial effect on the solar cell efficiency of Ruddlesden-Popper perovskites has unleashed an intensive research eff…
Photoluminescence mapping and time-domain thermo-photoluminescence for rapid imaging and measurement of thermal conductivity of boron arsenide
Shuai Yue, Geethal Amila Gamage, Mohammadjavad Mohebinia +14
Cubic boron arsenide (BAs) is attracting greater attention due to the recent experimental demonstration of ultrahigh thermal conductivity \k{appa} above 1000 W/mK. However, its ban…
Revealing the Origin of Luminescence Center in 0D Cs4PbBr6 Perovskite
Zhaojun Qin, Shenyu Dai, Viktor G. Hadjiev +13
Zero dimensional perovskite Cs4PbBr6 has attracted considerable attention recently not only because of its highly efficient green photoluminescence (PL), but also its two highly de…
Bright Luminescent Surface States on the Edges of Wide-bandgap Two-dimensional Lead Halide Perovskite
Yanan Wang, Chong Wang, Xinghua Su +9
Three-dimensional lead halide perovskites have surprised people for their defect-tolerant electronic and optical properties, two-dimensional lead halide layered structures exhibit…
