Thermally evaporated vanadium-based phthalocyanine for low moisture detection in humidity sensors
Aluminium / vanadyl 3,10,17,24-tetra-tert-butyl-1,8,15,22-tetrakis(dimethylamino)− 29 H,31 H-phthalocyanine (VTP) / Aluminium, (Al/VTP/Al) has been successfully studied for capacitive humidity sensing. The metal-containing vanadium central atom in the metal phthalocyanine has contributed towards exc...
