Witryna15 gru 1994 · Most chemical vapor deposited (CVD) diamond films contain impurities which increase their optical absorption in the regions of desired transparency. This paper examines the incorporation of these impurities, intentional or otherwise, and their effect on the IR absorption of CVD diamond, particularly in the 8–12 and 3–5 μm regions. Witryna1 mar 1996 · Introduction. When developing and validating methods of impurity determination, it is important to test the spectral peak purity (SPP) of the main substances using diode array detectors (DAD).Text.
