The high pressure experimental technique was employed to investigate the structural evolution of barlowite samples. The observed stepwise structural transformation from the initial hexagonal to the intermediate orthorhombic and the eventual monoclinic phase, is correlated with a continuous variation of the interlayer Cu occupation, the halide sizes, and the distortion of the kagome lattice within the system under pressure. The phase transition mechanism was also closely related with the combined contributions of an increase in external pressure and the cooperative intrinsic Jahn-Teller distortion.

Recent advancements in the field have introduced simultaneous multiband modulation, incorporating radiative cooling in the longwave infrared range. In this work, we present VO₂(M)/TiO₂(A)/ITO multilayer-coated glass (referred to as VTI) as a scalable and effective smart window that modulates both solar transmission and radiative cooling concurrently. As a semitransparent window in the solar spectrum, the VTI coating achieves nearly 100 % visual clarity, 38.5 % visible transparency, and 8.5 % modulation of solar transmittance. In the longwave infrared region, the VTI multilayer demonstrates an exceptional broadband emissivity shift of up to 42.5 %, made possible by an innovative Fabry-Pérot (F-P) cavity composed of absorbing metal oxides. This high degree of emissivity modulation is maintained across a wide range of spacer thicknesses, from 100 to 500 nm, as confirmed by both experimental data and simulations. The modulation mechanism of the F-P cavity which use ultrathin spacer (<em>λ</em>/140 ∼ <em>λ</em>/16) at its resonant absorption range is explained through incremental phasor analysis by the transfer-matrix method. Additionally, the scalability and practicality of the VTI film are supported by its three-layer composition and the room-temperature reactive magnetron sputtering deposition process.

In this study, a series of heteroatom-doped (LaPr)₂Ce₂O₇ ceramics are synthesized, with a defect fluorite structure, exhibiting differential infrared radiation properties over a broad spectrum. In particular, doping with low-valence transition metals (Cu and Co) introduces impurity levels and oxygen vacancies, effectively reducing the intrinsic bandgap and increasing emissivity at wavelengths below 6 μm. Meanwhile, the mismatched properties in mass and ionic radius between the dopants and host atoms increase the asymmetry of the lattice structure, which is beneficial for long-wavelength emissivity (&gt;6 μm). The infrared emissivity of (LaPrCu)₂Ce₂O₇ reaches 0.870 across a broad wavelength range from 0.78 μm to 16 μm, surpassing that of pristine (LaPr)₂Ce₂O₇. This enhancement is attributed to the effective collaboration of impurity absorption, free carrier absorption, and lattice absorption. More importantly, the achieved near black-body thermal emissivity at 1300 °C is suitable for applications in high-temperature thermal radiation. In contrast, the introduction of rare-earth elements (Gd and Ho) has a small impact on infrared emissivity due to their similar characteristics to La³⁺ and Pr³⁺.
