Abstract

The upconversion (UC) processes of infrared light to visible light of rare earth ions doped different hosts have been investigated extensively

due to their potential applications in some fields

such as solid-state lasers

display

communications

and so on. The recent researches emerging at the intersection of nanotech-nology and biotechnology are opening up a new period for the development of UC. As known

the controlled fabrication of a host with aimed structure is important for enhancing the upconversion efficiency

because the phonon energy of the host can affect the probabilities of non-radiative decay and the energy transfer. Therefore

it is necessary to choose a lattice with much lower phonon energy

which is benefit to the upconversion luminescence. Rare earth-doped hexagonal sodium yttrium fluoride (NaYF4) is a good host

which is known to be a very efficient near-infrared to visible upconverter. The hexagonal NaYF4 has low phonon energy. The structure of hexagonal phase gives rise to controversy about the cation sites and distribution. The trivalent thulium (Tm3+) is an ideal candidate for single wavelength NIR upconversion due to its ladder of nearly equally spaced energy levels that are multiples of the 1G4→3H6 transition. The development of compact blue lasers based on Tm3+ upconversion processes is nowadays widely studied mainly due to the potential of high perfor-mance OEM applications

such as biomedical and analytical instrumentation

display

photoprinting. In thu-lium doped media

the efficiency of this process is very low

but it was noticed that the mechanism could be made one or two orders of magnitude more efficient by using ytterbium(Yb3+). In this paper

trivalent thu-lium (Tm3+) and yttebium (Yb3+) ions codoped NaYF4 were synthesized by co-precipitation method. The concentration of Tm3+ and Yb3+ are 0.01%

0.1%

respectively. The absorption spectrum of NaYF4∶Tm3+

Yb3+ from 300 to 1 100 nm was measured at room temperature. The upconversion emission was observed when excited by 798 nm. The green and blue upconversion emission spectra were measured. Based on the experimental results the possible upconversion mechanism was analyzed. The main mechanism is the in-direct sensitization of Tm3+ and Yb3+. The blue emitting light results from the transition of 1G4→3H6 of Tm3+

green emitting light is from the transition of 1D2 →3F4 of Tm3+. To our knowledge

there have not been similar works published domestically and abroad. The structural properties of the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that NaYF4∶Tm3+

Yb3+ prepared by co-precipitation method exhibits hexagonal crystal phase.
