The Cu-Tm-App chelates are steadier in a weakly alkaline medium. A mobile phase with a pH between 8.2 and 11.8 avoids decomposing of chelates and gets a good peak shape. Also, tetra (m- aminophenyl) porphyrin (Tm-App) was synthesized and dissolved in THF to make a 1.5 × 10 -4 mol L −1 solution. For the Cu-Tm-App, the proper eluent is needed.

The phase diagram suggests that it is necessary to control the Cu sputtering rate and O 2 flow rate in order to form single-component Cu 2 O thin films. When the O 2 flow rate is more than the appropriate value for single component Cu 2 O, CuO forms in the Cu 2 O thin film, whereas when the O 2 flow rate is less than the appropriate value for ...
