摘要：A highly stable hydrophobic Ba2SiO4:Eu3+ (BSO) phosphor was produced by forming a robust hydrophobic inorganic silicon-oxy-imide-carbide layer on its surface. The process for developing this layer involved coating, ammonolysis, and pyrolysis of chlorosilane. The tightly adhered coating layer had a lotus, leaf-like micro- and nanohierarchical structure and contained CH3 groups, which enhanced the hydrophobicity of the modified phosphor significantly. The modified phosphors treated at 500 degrees C exhibited remarkable stability in their emission spectra, even after exposure to high-pressure water steam at 100 degrees C for 48 h, which is attributed to the high stability of the surface layer.
