Abstract :
The spray pyrolysis technique offers an extremely easy way to prepare thin films with dopants, virtually any element in any proportion by merely adding it in a spray solution. The simplified spray pyrolysis system contains precursor chamber, spray nozzle unit, electric heater, air compressor and spray-dry controlling unit. The aim of this work is to fabricate a cost effective automatic spray-dry controlling arrangement for the spray-pyrolysis system. The microcontroller based circuit is used in this controlling arrangement. It controls spray and dry time during thin film deposition which is given through keyboard by the user. A display unit has been interfaced with controller to become helpful for the user. An excellent performance have confirmed by using this controlling arrangement for depositing thin films by spray-pyrolysis technique. The proposed controlling system is easier to maintenance, low-cost and has no mechanical arrangement.
