Preparation and Properties of Borate PIG

Abstract: In recent years, the application of LED is become more and more widespread, this experiment will study the optical properties of various types of new PIG. First, high temperature melting quenching method was used to burn borate glass, and two kinds of PIG samples were prepared by high temperature melting method. The same concentration of phosphor Ce: YAG was mixed with different temperatures. And different concentrations of phosphor Ce: YAG was mixed with the same temperature. The emission spectra, emission spectra, color coordinate maps, light effects, color temperature and electrochromic spectra of borate PIG samples at different concentrations and different temperatures were tested and analyzed. The characteristics such as luminous intensity, emission performance, luminous color and influencing factors were also studied. Through this experiment, it shows that the samples are suitable for LED fluorescent materials and have potential applications and markets in the field of white LED light emission.
