Summary: | The present invention provides α-sialon phosphor particles which contain Eu. At least one slit is formed in the surface of each one of the α-sialon phosphor particles. It is preferable that the α-sialon phosphor particles are produced through a mixing step of starting materials, a heating step, a pulverization step and an acid treatment step.
La présente invention concerne des particules de phosphore alpha-sialon qui contiennent Eu. Au moins une fente est formée dans la surface de chacune des particules de phosphore alpha-sialon. Il est préférable que les particules de phosphore alpha-sialon soient produites par une étape de mélange de matières premières, une étape de chauffage, une étape de pulvérisation et une étape de traitement acide.
Euを含有するα型サイアロン蛍光体粒子。このα型サイアロン蛍光体粒子の表面には少なくとも1つのスリットが形成されている。このα型サイアロン蛍光体粒子は、好ましくは、原料の混合工程、加熱工程、粉砕工程および酸処理工程を経ることで製造される。 |
