Single crystal halide perovskites with microscale dimensions are an emerging class of objects for various advanced photonic and optoelectronic applications. Particularly, defect tolerance and broadband tunability of luminescence make them one of the most prospective candidates to develop microlasers for visible...
Here, we present hybrid perovskite single-crystal photodetectors that have a very narrow spectral response with a full-width at half-maximum of <20 nm. The response spectra are continuously tuned from blue to red by changing the halide composition and thus the bandgap of the single crystals ...
摘要: PURPOSE: To provide a light emitting material which allows intense emission oven a wide visible wavelength range covering blue, green and yellow and provide a material which has laser characteristics by adding V and Mg to perovskite crystal expressed as ALnAlO as laser activating ions....
The space-confined growth of thin monocrystals can be described by a two-step growth model (Fig.2a), which consists of the solute diffusion and the condensation of monomers on the crystal surface27. The accessibility of monomers at the crystal surface determines the crystal growth velocity28. W...
the single-crystal solar cells were illuminated by laser pulses (337 nm, 4-ns width from a SRS nitrogen laser) from the ITO side to generate a transient photovoltage signal which functions as a small perturbation to the background open-circuit voltage. The transient voltage signal was recorde...
Light soaking was achieved by coupling a green 532-nm laser diode (Thorlabs) into the microscope, yielding a soaking spot size of ∼10 μm and a power of ∼1 μW. A single-photon detecting avalanche photodiode (APD) (MPD PDM Series 50 mm) was used for the detection. The sample ...

The steady-state and time-resolved photoluminescence measurements of (PEA)2PbI4 single crystals were performed using a PicoQuant FT-300 with a 510-nm laser excitation source. Photoluminescence mapping measurement of (PEA)2PbI4 single crystals was performed using a PicoQuant FT-100. All PL spectra...
The outputs of the PBS are connected to single-photon detectors D1 and D2. The outcomes “0” or “1” of (M) are read by field programmable gate array (FPGA) electronics. b The structure of the employed perovskite diodes, with the biasing circuit indicated. The structure shows the ...
In the TPV measurement, the single-crystal solar cells were illuminated by laser pulses (337 nm, 4-ns width from a SRS nitrogen laser) from the ITO side to generate a transient photovoltage signal which functions as a small perturbation to the background open-circuit voltage. The transient...
