Abstract

∶ Ho

nanocrystals with efficient upconversion luminescence were prepared by solvent thermal method using glycol as solvent. The samples were characterized by X-ray diffraction(XRD)

transmission electron microscopy (TEM)

diffuse reflectance spectra

and upconversion luminescence spectra. XRD results indicate that the products are cubic phase. TEM images show that the In

∶ Ho

nanoparticles are sphere shape with an average size of 30 nm. The diffuse reflectance spectra give four narrow bands at 448

538

644 and 975 nm

corresponding to the

(448 nm)

(538 nm)

(644 nm) transitions of Ho

ions and

7/2

5/2

(975 nm) transition of Yb

ions. Under the excitation of 980 nm

∶ Ho

nanocrystals can emit strong green emission and weak red emission

corresponding to (

)

transitions of Ho

. Upconversion luminescence of In

∶ Ho

nanocrystals codoped with different concentrations of Ho

and Yb

ions were investigated to improve the luminescene intensity. The results show that the strongest upconversion emission can be achieved at a Ho

mole fraction of 3% and an Yb

mole fraction of 4%. The ln

-ln

curves show that both the green and red emissions are double-photon process and the possible mechanism is proposed.
