- •
Different alkaline-sodium-phosphate powders doped with Pr3+ have been fabricated.
- •
Change in quantitative composition leads to modification in luminescence behavior.
- •
Kubelka–Munk function analysis has been performed.
- •
The strong enhance of emission in red spectral scope has been observed.
- •
Upon 445 nm excitation, NaCaPO4:Pr3+ phosphor can be used as a promising material for red emission.
