A new crystal BO:3Al2O3:Gr3+, grown by Czoehralski method is reported. Absorption spectrum and fluorescence spectrum at room temperatures were measured. Three nm.sharp lines of fluorescence spectrum are at 695, 692.5,and 691 nm.4T2 emission is from 700 to 900nm. The crystal-field levels were calculated according to static electronic field model. The parameters such as crystal field, strength Dq, Eacach parameter B and C and E were calculated to be 1663, 643, 3180 and 589cm-1 respectively.
