Description

적색발광 형광체Red-emitting phosphor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는, 본 발명의 적색 발광 형광체의 발광 스펙트럼을 나타낸 특성도.1 is a characteristic diagram showing the emission spectrum of the red light-emitting phosphor of the present invention.

Claims (4)

Y2O3: Eu 적색 발광 형광체에 있어서의 모체 물질인 이트륨(Y)이, 란탄(La)와 실리콘(Si)로 미량 치환된 조성식(Yx Lay Siz)2O3: Eu로 나타내어지는 적색 발광형광체 (단, 상기식중, x,y,z0, x+y+z=1임).Y 2 O 3 : Red luminescence represented by compositional formula (Yx Lay Siz) 2 O 3 : Eu in which yttrium (Y), which is a parent material in the Eu red light-emitting phosphor, is substituted with a small amount of lanthanum (La) and silicon (Si) Phosphor (wherein x, y, z 0, x + y + z = 1). 산화이트륨(Y2O3) 및 산화유로피옴(Eu2O3)을 주원료물질로 하는 적색 발광 형광체의 제조 방법에 있어서,원료 물질로서 산화란탄(La2O3)및 및 산화실리콘(SiO2)를 추가하는 것을 특징으로 하는 조성식 (Yx Lay Siz)2O3: Ey로 나타내어지는 적색 발광 형광체의 제조방법 (단, 상기식중, x,y,z0, x+y+z=1임).In the method for producing a red light-emitting phosphor containing yttrium oxide (Y 2 O 3 ) and europium oxide (Eu 2 O 3 ) as main raw materials, lanthanum oxide (La 2 O 3 ) and silicon oxide (SiO 2 ) as raw materials ) Is a method for producing a red light-emitting phosphor represented by the composition formula (Yx Lay Siz) 2 O 3 : Ey (wherein x, y, z 0, x + y + z = 1). 제2항에 있어서, 산화란탄 및 산화 실리콘의 첨가량이 각각, 산화 이트륨의양에 대해 8-9중량%, 4,5-5중량%인 것을 특징으로 하는 조성식(Yx Lay Siz)2O3: Eu로 나타내어지는 적색 발광 형광체의 제조방법 (단, 상기식중, x,y,z0, x+y+z=1임).The compositional formula (Yx Lay Siz) 2 O 3 according to claim 2, wherein the addition amounts of lanthanum oxide and silicon oxide are 8-9% by weight and 4,5-5% by weight, respectively, with respect to the amount of yttrium oxide. Method for producing a red light emitting phosphor represented by Eu (wherein x, y, z 0, x + y + z = 1). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
