Abstract

A modified method to synthesize the new laser upconversion material Ba₂ErCl₇ using Er₂O₃, BaCl₂·2H₂O and NH₄Cl is reported for the first time in this paper. Single crystals up to 5-8 mm in diameter and 10-20 mm in length have been grown by Czochralski method. The transmittance spectra of Ba₂ErCl₇ single crystal has first been measured by using an HITACHI U-3500 spectrophotometer. There are three intense absorption peaks ⁴I_9/2, ⁴I_11/2 and ⁴I_13/2 in the infrared range which can be excited by 803 nm, 980 nm and 1.5 μm laser diodes (LDs), respectively. The cut-off wavelength of the crystal is 230 nm. Intense green luminescence can be observed when the crystal is pumped by a LD at 803 nm. The formation of the defects is also discussed.
