  We present a spectroscopic study of 150 Classical Be stars in 39 open
clusters 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 the
first time. All these candidates were identified from an extensive survey of
emission stars in young open clusters using slitless spectroscopy (Mathew et
al. 2008). This large data set covers CBe stars of various spectral types and
ages found in different cluster environments in largely northern open clusters,
and is used to study the spectral characteristics of CBe stars in cluster
environments. About 80% of CBe stars in our sample have H-alpha equivalent
width in the range -1 to -40 \AA. About 86% of the surveyed CBe stars show Fe
II 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-term
line profile variability in some candidate stars through repeated observations.
