Title:
PHOSPHOR, AND WAVELENGTH CONVERSION MEMBER AND ELECTRONIC DEVICE IN WHICH THE PHOSPHOR IS USED
Document Type and Number:
WIPO Patent Application WO/2018/055849
Kind Code:
A1
Abstract:
In this phosphor (25), a portion of the constituent elements of Na2MgPO4F are substituted with Ce3+ and/or Eu2+. In addition, the phosphor comprises a solid solution having Na2MgPO4F as a terminal component, the solid solution has the same crystal structure as Na2MgPO4F, and a portion of the constituent elements of the solid solution are substituted with Ce3+ and/or Eu2+. The phosphor has exceptional temperature properties even when ultraviolet light is converted to visible light. Further, this wavelength conversion member (20) and electronic apparatus are provided with the phosphor.
