Luminescence investigation of red emitting CaAlSiO4F: Eu3+ doped phosphor for white LEDs based on oxyfluoride matrix Open
A series of Eu3+-doped of CaAlSiO4F red-emitting phosphors for different concentrations were successfully synthesized by using high temperature solid state diffusion method. The phase identification of the prepared phosphor was recorded us…
