본 발명은, 하기 화학식 (I)의 업-컨버젼 인광체의 제조 방법으로서, A1-x-y-zB*yB2SiO4:Ln1x,Ln2z I 하기 단계: - 혼합물을 제조하는 단계, - 혼합물을 열 장치의 반응 챔버에 도입시키는 단계, - 열 처리 온도에 도달될 때까지 가열 램프를 사용하여 혼합물을 가열하는 단계, - 가열된 혼합물을 적어도 0.02시간의 유지 시간 동안 열 처리하는 단계, - 냉각 램프를 유지하면서, 열 처리된 재료를 실온으로 냉각시키는 단계, - 화학식 (I)에 따른 실리케이트계 란타노이드 이온-도핑된 인광체를 수득하는 단계 를 포함하는 방법에 관한 것이다. A process can be used for the preparation of an up-conversion phosphor of the general formula (I):A1-x-y-zB*yB2SiO4:Ln1x,Ln2z,   (I).The process involves preparing a mixture, introducing the mixture into a reaction chamber of a thermal apparatus, heating the mixture until a thermal treatment temperature is reached with a heating ramp, thermally treating the heated mixture for a holding time of at least 0.02 h, cooling the thermally treated material to room temperature while maintaining a cooling ramp, and obtaining a silicate-based lanthanoid ion-doped phosphor according to formula (I).
