The present work describes the first detailed gamma-ray responses of Ce3+ perturbed emission in CaF host. Ce3+ 1%" 3%, 5%, 10%, and 20% doped single crystalline CaF2 scintillators were grown by μ-PD method. Their transmittance were measured by JASCO V550 spectrometer, and about 80% transparence was achieved. All the sample showed an emission peak around 330 nm, which was Ce3+ perturbed emission, when they were irradiated by 1GBq 137Cs and read out by CCD. Absolute lihjt yield (ph/MeV) was measured by Si-APD (S866455, Hamamatsu), and the 3% sample showed the highest light yield around 900 ph/MeV with 2us shaping time. The decay time was measured by FLS900 (Edinburgh instrument), and about 40 ns decay was observed.
