چکیده انگلیسی
â¶ Sol-gel process was adopted to encapsulate the as-prepared Ca3SiO4Cl2:Eu2+ phosphors with tetraethylorthosilicate (TEOS) as silicon coating reagent in order to enhance the chemical and thermal stability. â¶ The water-resistance stability of the coated phosphor was improved to some degree because the pH value and the luminance intensity variation were both smaller than the uncoated phosphor after steeping within the same time. â¶ The thermal stability of coated phosphors was enhanced obviously compared to the original samples based on the temperature dependent emission spectra measurement.
