Preparation of remote glass fluorescent film by screen printing

Abstract：This paper presents a simple and practical method for preparing phosphor glass. Screen printing technology provides the possibility of design and engineering of composite phosphor layers on glass substrates. Fluorescent screen printing technology allows for the realization of high stability and thermal conductivity of the phosphor layer. This method of fluorescent glass provides more possibilities for LED packaging to achieve remote phosphor technology. In this experiment， the glass powder prepared by the experiment was used as raw material and dispersed in terpineol and ethyl cellulose to prepare the slurry with the experimental conditions. The YAG borate-doped glass fluorescent film was successfully prepared by screen printing. The YAG borate doped glass fluorescent film was successfully prepared by screen printing method. The PL spectra and PLE spectra of YAG borate were tested， and the luminescent properties of the glass were characterized. The influence of the temperature and the concentration of YAG was investigated.
