abstract = "Hot filament chemically vapor deposited (HFCVD) boron doped
diamond films were grown on monocrystalline silicon (111) doped
with B/C ratios of 4000, 8000 and 12,000 ppm. Scanning electron
micrographs show that the films are composed of well-faceted
microcrystallites ranging in size from about 1 to 5 mu m with no
correlation with B/C concentration. The Raman spectra exhibit a
sharp diamond band at 1332 cm(-1) which shifts to lower wave
numbers, broaden and decreases as the B/C ratio increases. An
additional broad band is observed around 1200 cm(-1). The beta
irradiated diamond films exhibit thermoluminescence (TL) and
optically stimulated luminescence (OSL) and the TL glow curves can
be fitted well with four glow peaks. The kinetic parameters of
these TL peaks as well as their intensities depend on B/C ratio.
The OSL curves of the diamond films grown with 4000 and 8000 ppm
of B/C exhibit standard decay behaviour for continuos stimulation
with light of 470 nm. However, the OSL signal of the 12,000 ppm
film increases initially with light stimulation, reaching a
maximum to decay afterwards. (c) 2005 WILEY-VCH Verlag GmbH \&
