“…The advent of hydrothermal synthesis has made sudden progress in the field of preparation, which not only greatly reduces the temperature of the reaction, but also enables the synthesis of products in a single step. In recent years, Yang, 120 Ankoji, 121 Wang, 122 and other teams have successfully prepared different LPPs with excellent afterglow properties using this method using high-temperature and high-pressure reactors. The synthesis conditions in this method are mild, and the particles are nanoscale and uniform.…”

“…Rare earth LaAlO 3 with an ABO 3 crystal structure is a material that has attracted a lot of attention in recent years due to its unique properties. Its high melting point [1][2][3], chemical stability [4,5], and large band gap (3.8 eV) [6][7][8] make it a promising material for various applications. If the radius of the doping ion is close to La 3+ or Al 3+ , LaAlO 3 , an essential cubic perovskite oxide, can be doped with significant concentrations of ions through substitution [9][10][11][12].…”

This work involves the introduction of niobium oxide into lanthanum aluminate (LaAlO3) via a conventional solid-state reaction technique to yield LaAlO3:Nb (LaNbxAl1−xO3+δ) samples with Nb5+ doping levels ranging from 0.00 to 0.25 mol%. This study presents a comprehensive investigation of the effects of niobium doping on the phase evolution, defect control, and reflectance of LaNbxAl1−xO3+δ powder. Powder X-ray diffraction (XRD) analysis confirms the perovskite structure in all powders, and XRD and transmission electron microscopy (TEM) reveal successful doping of Nb5+ into LaNbxAl1−xO3+δ. The surface morphology was analyzed by scanning electron microscopy (SEM), and the results show that increasing the doping concentration of niobium leads to fewer microstructural defects. Oxygen vacancy defects in different compositions are analyzed at 300 K, and as the doping level increases, a clear trend of defect reduction is observed. Notably, LaNbxAl1−xO3+δ with 0.15 mol% Nb5+ exhibits excellent reflectance properties, with a maximum infrared reflectance of 99.7%. This study shows that LaNbxAl1−xO3+δ powder materials have wide application potential in the field of high reflectivity coating materials due to their extremely low microstructural defects and oxygen vacancy defects.
