NOVELTY - A transparent conducting film (F1) comprises doped zinc metal oxide derivative.    USE - In transparent conducting coating e.g. an antistatic coating, an optical coating, a heat-reflecting coating, an antireflection coating, an electromagnetic interference shield, a radio-frequency interference shield, an electrowetting coating, or a coating for a display, for a touch panel or for a sensor, used in an organic light-emitting device, an electroluminescent display device, a solid-state light, a photovoltaic device, a solar cell, a photodiode, a transparent electronic device, an electrode, a display, a touch panel, a sensor, a window, flooring material, a mirror, a lens, a Bragg reflector, a strain gauge or a radio-frequency identification (RFID) tag; in display comprising liquid crystal display, an electrochromic display, a flat panel display, a plasma display, electronic paper or a field emission display; and for coating polymer or glass (all claimed) used in flexible electronics applications. Also used as A heat-reflecting coating e.g. a coating for a window, and an architectural or automotive window. Such heat-reflecting coatings are also used in vapor lamp glasses.    ADVANTAGE - The transparent conducting films of doped zinc oxides have temperature-stable electrical and optical properties which are comparable to those of Sn-doped In2O3 thin films. The doped zinc oxide films are attractive for transparent conductor applications as they are easy to produce from inexpensive, abundant precursors, and are non-toxic. The zinc oxide has a higher visible transmittance than many other conductive oxide films and is more resistant to reduction by hydrogen-containing plasma processes that are commonly used for the production of solar cells. Zinc oxide itself is also inexpensive, abundant in nature and non-toxic. It also has certain properties which are considered important for transparent conductors, such as a band gap of 3.4 eV, an intrinsic carrier concentration of 106 cm-3 and an electron Hall mobility of 200 cm2V-1S-1. The films have reduced amount of indium.    DETAILED DESCRIPTION - A transparent conducting film (F1) comprises doped zinc metal oxide derivative of formula Zn1-x(M')xO1-y(X)y(I).    x=0-0.25;    y=0-0.1;    X=dopant element which is halo;    M'=dopant element selected from group 14 element other than carbon, lanthanide element having oxidation state of +4, and/or transition metal having oxidation state of +4 and which is other than Ti or Zr.    INDEPENDENT CLAIMS are included for the following:    (1) production (P1) of the transparent conducting film (F1) involving producing the film by pulsed laser deposition;    (2) transparent conducting coating comprising the transparent conducting film (F1).
