We present a spectroscopic study of 150 Classical Be stars in 39 openclusters using medium resolution spectra in the wavelength range 3800 - 9000\AA. One-third of the sample (48 stars in 18 clusters) has been studied for thefirst time. All these candidates were identified from an extensive survey ofemission stars in young open clusters using slitless spectroscopy (Mathew etal. 2008). This large data set covers CBe stars of various spectral types andages found in different cluster environments in largely northern open clusters,and is used to study the spectral characteristics of CBe stars in clusterenvironments. About 80% of CBe stars in our sample have H-alpha equivalentwidth in the range -1 to -40 \AA. About 86% of the surveyed CBe stars show FeII lines. The prominent Fe II lines in our surveyed stars are 4584, 5018, 5169,5316, 6318, 6384, 7513 and 7712 \AA. We have identified short and long-termline profile variability in some candidate stars through repeated observations.
