Patent number: 9758721Abstract: A core-shell fluorescent material and a light source device using the same are disclosed. The core-shell fluorescent material includes a core and a shell for generating an emitting light with wavelength within 520 and 800 nm after absorbing an exciting light with wavelength within 370 and 500 nm. The core may include yellow, green or red fluorescent powder, and the shell includes manganese (IV)-doped fluoride compound. The light source device generally includes the core-shell fluorescent material, a radiation source, leads and a package. The leads provide current to the radiation source and cause the radiation source to emit radiation. The core-shell fluorescent material is coated on the package for receiving the radiation so as to generate a high quality emission served as the desired light source for the field of lighting and displaying.Type: GrantFiled: March 24, 2015Date of Patent: September 12, 2017Assignee: CHINA GLAZE CO., LTD. (TAIWAN)Inventors: Chia-Hung Tseng, Yi-Cheng Chiu, Sung-Yu Tsai, Hsien-Chung Tsai

Patent number: 8871339Abstract: 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.Type: GrantFiled: February 27, 2009Date of Patent: October 28, 2014Assignees: Chung Yuan Christian University, China Glaze Co., Ltd.Inventors: Tsung-Yen Tsai, Shau-Tai Lu, Chia-Hsiang Liu, Chun-Chieh Huang, Hsien-Chung Tsai, Jen-Chun Lin

Patent number: 8747696Abstract: 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.Type: GrantFiled: November 26, 2010Date of Patent: June 10, 2014Assignee: China Glaze Co., Ltd.Inventors: Jen-Chun Lin, Su-Ren Wang, Pei-Chun Tsai, Kuo-Ju Chen, Chun-Che Lin, Ru-Shi Liu

Patent number: 6080454Abstract: A process for producing stained crystallized glass and its articles is provided where crystallized glass is obtained with patterns and colors like that of granites, marble, and other natural stones. The process includes the heat-treatment of a prepared batch of crystallizable glass granules, colored powder and water, at a temperature higher than the softening point of the glass granules resulting in fusion bonding of the glass granules. The colored powder is compounded by an inorganic pigment, a suspension stabilizing agent, an agglomerate, a deflocculant agent, and a crystallizable glass powder. The surface pattern is formed by the grain boundary region of the crystallizable glass granules, and part of the inorganic pigment in the colored powder moving with the crystallizable glass powder.Type: GrantFiled: September 22, 1997Date of Patent: June 27, 2000Assignee: China Glaze Co., Ltd.Inventors: Kuo-Chuan Hsu, Ching-Hsi Lin, Hsien-Chung Tsai
