Phosphate glasses doped with Mn⁴⁺ ion were prepared using high temperature melting method. Under 408 nm excitation, the peak wavelength and lifetime of the fluorescence are related to the Mn⁴⁺ ion concentration. With the increasing of Mn⁴⁺ ion concentration, the fluorescence wavelength varies from 605 nm to 685 nm and the lifetime increases from several microseconds to one millisecond. The fluorescence wavelength is variable and the lifetime is tunable for our materials.
