vadodara anand this innovation promises to make your cell phones tablets computers and television sets cheaper and that too while providing better display of colours on screensa team of researchers from the chemistry department of sardar patel university spu has developed metal complexes which are cheaper than the organic lightemitting diodes oleds used currently in the display unit of electronic gadgets like cell phones tablets and television sets the device prepared using these metal complexes provides better colour purity and its fabrication process too is costeffective oleds are laminationbased materials which are currently used in gadgets as lightemitting materials said dr kirankumar surati associate professor at the department who led the team that recently received a patent for the research project but the existing oleds are less stable the metal that is currently used is very costly life of the device is short and there are problems of colour bleaching for example blue colour in the display starts fading and turns to sky blue or whitish said surati we have developed heteroleptic iridium iii complexes a type of metal complex these metal complexes are costeffective stable have a higher life and have the ability to generate pure colour he said just one gram of commercially available compounds that are currently used in electronic gadgets cost more than rs 50000 whereas the compounds developed by spu team costs less than half the compounds were developed as part of a project funded by the department of science and technology we are in talks with some industrial players to transfer the technology so that it can be commercialized he said the new material is not only costeffective but can be easily used for creating a display of gadgets
