Problems solved by technology

However, most of the research work in related fields revolves around the doping modification of existing reported compounds, or studies on a series of isomorphic compounds of more mature substrates, while the work on exploring new substrate materials is relatively rare.
[0004] In addition, the high-temperature solid-phase method is currently the most commonly used production method for phosphors, but this method has disadvantages such as high synthesis temperature, long reaction time, and high energy consumption.
