With a total of four patents to his name, Tsai's work has implications for various applications in lighting and display technologies.

Latest Patents

One of Tsai's latest patents is focused on a core-shell fluorescent material and a light source device that utilizes this innovative material. The core-shell fluorescent material consists of a core and a shell, which together generate emitting light with wavelengths ranging from 520 to 800 nm after absorbing exciting light with wavelengths between 370 and 500 nm. The core may contain yellow, green, or red fluorescent powder, while the shell is made from a manganese (IV)-doped fluoride compound. The light source device incorporates this core-shell fluorescent material, along with a radiation source, leads, and a package. The leads supply current to the radiation source, enabling it to emit radiation. The core-shell fluorescent material is applied to the package to receive the radiation, producing high-quality emissions suitable for lighting and display applications.

Another notable patent by Tsai involves a modified clay and a clay-polymer composite. This modified clay features a layered clay material intercalated with a modifier that has a conjugated double bond and can generate free radicals when heated. The clay-polymer composite includes a polymer material and the modified clay, which is dispersed and partially exfoliated within the polymer. The modifier's ability to produce free radicals when heated helps to scavenge free radicals generated from the thermal cracking or burning of the polymer material, thereby preventing further degradation.
