Growth and Spectrum Properties of Ho:BaY₂F₈ Crystal

Abstract:

Ho³⁺:BaY₂F₈(Ho:BYF) single crystal was grown by the Czochralski method. The optimal technical parameters obtained are as follows: the pulling rate is 0.5mm/h, the rotation rate is 5rad/min, the cooling speed is 10°C/h.The result of XRD curve shows that as-grown Tm:BYF crystal belongs to the monoclinic system and space group C12/m1. The cell parameters calculated are a=0.642nm,b=1.03293nm,c=0.42621nm,β= 99.62o.The absorption and fluorescence spectra of the Ho:BYF crystal were measured.FWHM is 8 nm on 884 nm wavelength,absorption coefficient and absorption cross-section calculated are 1.21cm^-1 and 1.21×10^-21cm².
