The authors develop a method for the production of ultra-bright, efficient and stable perovskite light-emitting diodes, achieved with a simple in situ reaction process. Joo Sung Kim , Jung-Min Heo & Tae-Woo Lee Article 28 September 2022 | Open Access Extending the spectrum of fully integ...
In Fig.3h, we plot the device EL spectrum (red line;VG = +0.5 V andVSD = +2.2 V) together with the PL spectrum of 4L-InSe (purple line; PL is measured atT = 5 K, since no signal is observed at room temperature) and 2L-WS2(blue line). The energy of ...

leaving holes in the valence band for oxidation reaction. Wide-bandgap semiconductors only absorb UV light (wavelength (λ) < 420 nm), which accounts for a very small fraction (∼ 5%) of solar spectrum[7,8,281]. In contrast, narrow-bandgap semiconductors extend the light absorption ...
This Si-LED emitted light in the 1.4 eV photon energy (0.9 渭m wavelength) band, and phonon sidebands were observed in the emission spectrum. From a... M Yamaguchi,T Kawazoe,M Ohtsu - 《Applied Physics A》 被引量: 11发表: 2014年 Comparison of Positron Emission Tomography and Lymphangiog...
in related field of light-to-thermal conversion. However, because of its wide band gap (3 eV), it can only absorbultraviolet lightwith wavelengths <400 nm[95,96]. In order for TiO2to efficiently utilize the full spectrum of sunlight, strategies are needed to narrow its band gap. At ...

spectrum analyzer, and the\(V_\pi\)was estimated by fitting the sideband powers using a Bessel function,\(| {J_n( {\pi \frac{V}{{V_\pi }}} )} |^2\), wherenis the sideband number,\(V\)is the drive voltage. The measured\(V_\pi\)as a function of frequency is shown in ...
Simultaneous X-ray and Radio Monitoring of the Unusual Binary LSI+61 303: Measurements of the Lightcurve and High-Energy Spectrum The binary system, LSI+61 303, is unusual both because of the dramatic,\nperiodic, radio outbursts, and because of its possible association with the 100\nMeV gam...
