“…Similarly, magnesium exhibits the ability to modulate the morphology of VO 2 . 127 As shown in Fig. 8c, without doping with Mg, VO 2 has a club-like structure, while the VO 2 nanoparticles show a snowflake structure with the branch growing along the [110] direction when the Mg doping concentration is 0.5–2.0 at%.…”

“…The lower the haze measurement value, the higher the clarity of the sample. According to the standard method of ASTM Method D1003 for haze measurements, the haze value can be calculated using the following equation , where T 1 is incident light, T 2 is the total transmittance of the specimen, T 3 is the light scattered by the instrument, and T 4 is the light scattered by the specimen and the instrument.…”

High-quality VO2 nanoparticle (NP) films were prepared by a facile self-template synthesis method, including sputtering of V films and postannealing, and were identified as a parabolic nanocone array, namely, the moth-eye nanostructure. Compared to a VO2 flat thin film with a refractive index of ∼3 at a 550 nm wavelength, the fabricated subwavelength VO2 NP films with the graded and lower effective refractive index (less than 2) exhibited ultrahigh luminous transmittance (T lum) due to the decreased reflectance differences at air/VO2 and VO2/glass interfaces. Meanwhile, subwavelength rutile VO2 NPs provided the localized surface plasmon resonance excited at ∼1250 nm wavelength to enhance the solar modulation (ΔT sol). Using simulations, the optimal NP size and porosity of the NP film were designed to obtain the optimum balance between ΔT sol and T lum, which were confirmed by experimental results. The single-sided VO2 NP film with an ultrahigh T lum of 93.3% exhibited a transparent vision with a ΔT sol of 6.1%, and the double-sided VO2 NP film provided an excellent ΔT sol of 14%, while the T lum remained at ∼70%. The outstanding performances of the VO2 NP films exceeded the reported results for porous films, multilayers, and nanostructures. Thus, we believe that the VO2 NP film is a promising nanostructure to lead VO2-based coatings to an era for smart window applications, including the building glazing and windshields of vehicles.

“…The LSPR can be reversibly switched on by elevating the temperature to transit VO 2 from insulating to the metallic state while being entirely quenched at a lower temperature (Figure a). Also, the LSPR in VO 2 is affected by the local media reflective index, , crystal sizes, and particle shapes (Figure b). , Above the critical transition temperature, the nanoparticles exhibit a strong electrical field near their interfaces (Figure c). In their following work, they verified that the particle size and W dopants are effective to control the LSPR energy (Figure d,e), for example, the energy decreases to ∼0.7 eV on the sample with a W doping level of 10 at.…”

Phase transitions can occur in certain materials such as transition metal oxides (TMOs) and chalcogenides when there is a change in external conditions such as temperature and pressure. Along with phase transitions in these phase change materials (PCMs) come dramatic contrasts in various physical properties, which can be engineered to manipulate electrons, photons, polaritons, and phonons at the nanoscale, offering new opportunities for reconfigurable, active nanodevices. In this review, we particularly discuss phase-transition-enabled active nanotechnologies in nonvolatile electrical memory, tunable metamaterials, and metasurfaces for manipulation of both free-space photons and in-plane polaritons, and multifunctional emissivity control in the infrared (IR) spectrum. The fundamentals of PCMs are first introduced to explain the origins and principles of phase transitions. Thereafter, we discuss multiphysical nanodevices for electronic, photonic, and thermal management, attesting to the broad applications and exciting promises of PCMs. Emerging trends and valuable applications in all-optical neuromorphic devices, thermal data storage, and encryption are outlined in the end.
