Site occupancy strategy for emission tunable K3HF2W1-xOF6:xMn4+ nanophosphor via ions exchange
A novel uniformly ellipsoidal K3HF2W1-xOF6:xMn4+ nanophosphor were demonstrated by ion exchange method without K2MnF6. The samples had wide excitation range from ultraviolet to visible light and tunable emission spectra from green to red were obtained which can be regulated by the emitting spectra o...

| description | A novel uniformly ellipsoidal K3HF2W1-xOF6:xMn4+ nanophosphor were demonstrated by ion exchange method without K2MnF6. The samples had wide excitation range from ultraviolet to visible light and tunable emission spectra from green to red were obtained which can be regulated by the emitting spectra of K3HF2WOF6 host and Mn4+. Energy transfer efficiency from [WOF6]2− to Mn4+ were improved with the increase of Mn4+. The peak position of thermal stability spectra of K3HF2WOF6 were blueshifted while Mn4+ doped samples undergoes a redshift. The crystal field strength and the Racah parameters were estimated and luminescence mechanism was explained by the Tanabe–Sugano energy level diagram of the Mn4+. Microsecond fluorescence lifetime indicates it advantages in fast react displays to avoid ghost images. The results indicate that K3HF2W1-xOF6:xMn4+ nanophosphor has potential application in display, converting phosphors for UV and blue LED and indoor plant supplyment light. |
