Preparation and properties of a high-entropy amorphous oxide with high refractive index by containerless solidification

Tunable ultra‐wideband NIR emission and irradiation resistance in novel Er3+/Tm3+/Pr3+ tri‐doped La2O3‐ Ga2O3‐Ta2O5 glasses synthesized using aerodynamic levitation method

“…Generally, the hardness ( H v ) of the material is positively related to the wear resistance, and it can be clearly observed that H v values show no obvious change in the range of 7.31–7.93 GPa when x rises from 20 to 55. The H v of glasses attains an utmost value (7.93 GPa) when x = 30, which is evidently larger than La‐Ti‐Nb‐W‐Zr glasses (7.22 GPa), 21 indicating that the synthesized samples have high wear resistance and good impact resistance. The related values are listed in Table 1.…”

Physicochemical Properties of High‐Entropy Oxides

“…Recently, more and more researchers are devoted to improving the refractive index and transmittance of HEO. [14,111,[128][129][130][131] Zhang et al have reviewed synthesis, fabrication, and application of the high-entropy transparent ceramics in detail. [132] It is conceivable that this high transparency of HEO, combined with other superior properties, can provide more functional possibilities and is a prospective candidate for future multifunctional materials.…”

“…Therefore, it is urgent to seek material with both low thermal conductivity and large Seebeck coefficient simultaneously. The summarization of thermal conductivity and Seebeck coefficient of SrTiO 3 ‐based thermoelectric materials is shown in Figure 7(f), including Sr 0.9 La 0.1 (Zr 0.25 Sn 0.25 Ti 0.25 Hf 0.25 )O 3 , [100] La 0.1 Dy 0.1 Sr x TiO 3 , [108] Ag‐SrTiO 3 , [109] La−Nb co‐doped SrTiO 3 , [94] Nb‐doped SrTiO 3 , [110] La−Dy‐Nb co‐doped SrTiO 3 , [111] La‐doped SrTiO 3 , [112] Ta‐substituted SrTiO 3 , [113] RGO‐SrTiO 3 , [114] Ti‐Sr 0.9 La 0.1 TiO 3 , [115] and Sr(Ti 0.2 Fe 0.2 Mo 0.2 Nb 0.2 Cr 0.2 )O 3 [99] …”

“…To fabricate transparent ceramics, the sample particles must undergo a series of heat treatments to remove all internal pores and achieve full densification. Recently, more and more researchers are devoted to improving the refractive index and transmittance of HEO [14,111,128–131] . Zhang et al.…”
