| titleOfInvention | A oxide-based red phosphor for fluorescent display and a preparation method thereof |
| abstract | TECHNICAL FIELD The present invention relates to display device technology, in particular red for fluorescent displays. The present invention relates to a fluorescent substance and a method for manufacturing the same, and red for fluorescent displays having high luminous efficiency and high color purity even at low voltage due to no desorption of sulfur even with long-term electron scanning and less deterioration. It is intended to provide a phosphor and a manufacturing method which can produce the same simply and economically. The present invention relates to Ga as a dopant. 3+ , Li + By adding the initial reactant SrCO 3 Or SrO and TiO 2 Synthesized from SrTiO 3 Pr, an activator, by modifying its structure 3+ This increases the excitation efficiency of, thereby improving the luminance of the phosphor and having a single emission band, thereby obtaining a red phosphor having excellent color purity. That is, according to the present invention, the initial reactant SrCO 3 Or SrO and TiO 2 Instead of adjusting the composition ratio of to 1: 1 ratio, Ga 3+ , Li + By adding ABO 3 A portion of Sr or Ti at the A or B position of the perovskite having a crystal structure 3+ and Li + Pr by modifying the microstructure 3+ To increase the excitation efficiency of + Brightness can be further improved by adjusting the addition amount and the reaction temperature of the particle size (particle size) and the shape (particle shape). |
