Abstract
A method of producing a nitride fluorescent material having relatively high light emission intensity is provided. The method of producing a nitride fluorescent material includes preparing a calcined product having a composition containing at least one first element selected from the group consisting of Ba, Sr, Ca, and Mg, at least one second element selected from the group consisting of Eu, Ce, Tb, and Mn, and Si and N, and bringing the calcined product into contact with a fluorine-containing substance at a temperature in a range of −20° C. or higher and lower than 150° C.
