Adjustable wavelength and lifetime in Mn4+ ion doped phosphate glasses

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 6...

Description
Summary: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. •The peak wavelength of the fluorescence depends on the Mn4+ ions concentration.•The lifetime changes from a few microseconds to one millisecond with the increasing of Mn4+ ions concentration.•The emission intensities of the materials are very strong.
