Published in 2019 at "Ceramics International"

DOI: 10.1016/j.ceramint.2019.06.268

Abstract: Abstract We have employed the solid-state chemical reaction to construct series of trivalent erbium ions activated NaLaP 4 O 12 (abbreviated as: NLP) phosphors. The structural investigation indicates that NLP:Er 3+ crystalline products are purely… read more here.

Published in 2018 at "Electrochimica Acta"

DOI: 10.1016/j.electacta.2018.06.111

Abstract: Abstract Extending the spectral absorption of dye-sensitized solar cells from the visible into near-infrared and ultra-violet range enables the minimization of non-absorption loss of solar photons. Here, we report a viable strategy to implement simultaneously… read more here.

Published in 2021 at "Journal of Renewable and Sustainable Energy"

DOI: 10.1063/5.0044654

Abstract: To better suit the bandgap of solar cell, we proposed a novel theoretical model of solar thermophotovoltaic system, which consists of a concentrator, a surface-textured absorber, an emitter, a photovoltaic cell, and a downconversion layer.… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.447674

Abstract: Comet-tail-like interference patterns are observed using photons from the spontaneous parametric downconversion (SPDC) process. The patterns are caused by the angular-spectrum-dependent interference and the diffraction of a blazed grating. We present a theoretical explanation and… read more here.
