Synthesis nano particles for various pH or different temperature? what happen in the UV spectrum of absorbance and transmittance, what concept behind there ?
Can you clarify your question, it's not clear, what type of your nasnoparticles and how much temperature and pH are change. In general, change of temperature and pH may have an effects on morphology of nanoparticles.Factors that may cause shift in UV spectrum of nanoparticles are existence of dopnats and annealing temperature .

Dear prabu , yes pH and temperature changes cause significant changes in size , shape and morphology of nanoparticles but it depends totally on atomospher ,environment ,nature of i.e precursor, reducing agent , caping agent , medium and their concentrations as well , where nanoparticles are going to form , for example in case of high temprature, in specific nanoparticles more ionization take place which produces bulk of ions results more ions reduce by reductant ,more atoms form in system nad at high temperature caping agent does not work properly in some cases which cause rapid agglomeration even some time aggregation which leads bigger particles may be not in nano range .hope this short explanation will clear your idea .
