A modified clay is provided, which includes a layered clay material intercalated with a modifier having a conjugated double bond and capable of producing free radicals when heated. A clay-polymer composite is also provided, which includes a polymer material and the modified clay, wherein the modified clay is dispersed in the polymer material and at least partially exfoliated. The modifier is capable of producing free radicals when heated to scavenge free radicals generated from thermal cracking or burning of the polymer material to prevent further thermal cracking of the polymer material.

Modified clay and clay-polymer composite

Disclosed are compositions and synthetic methods of phosphors that can be efficiently excited by blue light. The wavelength of the blue light is between 400 nm to 480 nm. The phosphors contain garnet fluorescent material activated with cerium, which contain Ba, Y, Tb, Lu, Sc, La, Gd, Sm, or combinations thereof, and Al, Ga, In, or combinations thereof. In addition, the phosphors are easily and quickly prepared in a large amount. The phosphors have high thermal stability and high emission intensity, therefore, being high of value in industry for utilization.
