Phosphor heat-transfer method and apparatus therefor |
摘要 |
A phosphor heat-treating method and an apparatus therefor capable of providing a phosphor exhibiting improved crystallizability and increased in concentration of a luminous center therein. A phosphor is heated and rapidly cooled in atmosphere gas of a predetermined pressure. The pressure substantially restrains decomposition and scattering of the phosphor during heating and cooling of the phosphor.
