We present optical reflectivity data in optimally doped and underdoped PCCO thin films. The optical conductivity of the underdoped sample presents an unconventional increase around 2000 cm À1 when lowering the temperature. Spectral weight is transferred from low (0-3000 cm À1 ) to high (3000-6000 cm

✦ Synopsis
Low temperature heat capacity was measured as a function of x in Pr2_xCexCuO #. The temperature linear term, yT, increases linearly, and the Debye temperature decreases with x. The Einstein contribution to the heat capacity is large and decreases gradually with electron-doping.
