The general objectives of this project are:
(1) elaboration, performing and validation of the technology for the synthesis of innovative nanostructured optical materials having efficient temperature sensing properties based on luminescence in NIR (Near Infrared) domain and,
(2) achieving an experimental demonstrative setup followed by a smart prototype device, which incorporate the nanostructured optical materials with performing temperature sensing properties.
The specific objectives of the project are the following:
(i) to develop a laboratory solgel technology for the preparation of innovative PbS and PbSe QDsdoped phosphatesilicate thin films deposited by: a) spin coating technique on planar substrates (silicon/glass/quartz), and, as an alternative route, by b) dip coating technique in which the deposition occurs on optical fibers.
(ii) to investigate the luminescence properties in dependence on temperature (up to 400oC), correlated with the quantum confinement effect of PbS and PbSe QDs embedded in phosphatesilicate thin films with complex composition (Al2O3, TiO2, ZnO, ZrO2 are added to improve the chemical and thermal properties).
(iii) to perform an experimental demonstrative setup followed by the prototype device that incorporate the innovative PbS and PbSe QDsdoped phosphatesilicate thin films with complex composition, showing the performant sensitivity to measure the environmental temperature changes, based on NIR luminescence variation.
