a, b Photographs and spectra of PL from CaGa4O7:Mn2+ heated from 298 K to 623 K. c Relative PL intensity of blue emission (blue squares) and yellow emission (yellow cycles) during the heating (298 − 623 K) and cooling (623 − 298 K) cycle. d Representative XRD patterns of CaGa4O7:Mn2+ heated from 298 K to 523 K and subsequently cooled to 298 K. e ThL curve of CaGa4O7:Mn2+. The inset shows the ThL spectrum collected during heating. Source data are provided as a Source Data file.
