Abstract In response to the urgent demand for windows with multi‐mode self‐calibrated temperature feedback operating over a wide range in extreme environments, herein, Pr 3+ –Er co‐doped Y 2 Zr O 7 (YZO) transparent ceramics were developed. After annealing treatment remove defects, these exhibit high transparency and temperature‐dependent wide‐range photoluminescence, which in‐line transmittance is up 77.8% at 760 nm (theoretical limit 78%), luminescence band spans blue red. Furthermore,...
Pr-doped metal oxide polycrystalline transparent ceramics are highly desirable for photothermal window systems served in extreme environments; however, obtaining efficient photoluminescence (PL) together with high transparency these is still posing serious challenges, which undoubtedly limits their applications.

This paper describes an original and facile polyol-mediated solvothermal synthesis of elliptical iron glycolate nanosheets (IGNSs) combined with precursor thermal conversion into γ-Fe2O3 α-Fe2O3/γ-Fe2O3 porous (PNSs), α-Fe2O3 nanochains (NCs), Fe3O4 nanorings (NRs). The IGNSs were produced via the oxidation–reduction co-precipitation reactions in presence iron(III) salts, ethylene glycol, polyethylene ethylenediamine. Control over Fe3+ concentration, temperature, time can considerably...
