Dear Jayaramakrishnan,

one optical method of choice to study crystallization from solution is an adapted version of laser confocal microscopy. It provides a mesoscopic spatial resolution on a crystal-wide scale, ideally suited to study growth mechanisms of crystals. Perhaps the following book chapter may be of interest to you:

thank you mike, i will refer your book chapter and search my answer. I hope your book chapter may help to me

with warm regards,

Dear Jayaramakrishnan,

please have a look on conventional Atomic Force Microscope (AFM). You will find plenty studies on this. Have a look in the attachment also.

Kind regards,

Dear E.Arvaniti,

Thank you for your kind information and I hope this attachment is very useful for my studies.

Dear Jayaramakrishnan,

I would suggest using hot stage microscopy, in which you can melt the crystals and observe their formation during cooling from their solution while measuring time during the process. This in simple words, gives you the crystal growth rate (time VS size of crystals which can be measured using micro scale).

By the way, you will need to use crossed-polarisers and work out to find the angle at which the Spherulites can be characterized.

Hi,

To gain a better understanding of the mineral world is important to understand well the mechanisms of crystal growth, as these processes are crucial for the main features of crystalline materials, such as morphology. But I also understand the growth mechanisms we can provide information on the evolution and the conditions under which the crystals appeared and help better understand the geological events involved in the formation of mineral deposits and regional geological history.

To study the mechanisms of crystalline materials growth is very important in situ observation of these processes. For the quantitative characterization of crystal growth has been used mainly two well known techniques: Atomic Force Microscopy (AFM) and Phase Shifting Interferometry (PSI). But recently it has developed a new technique called Confocal Microscopy with Differential Phase Contrast (LCM-DIM), which allows to study the mesoscopic scale crystal growth. With this technique it is possible to observe the dynamics of the elementary steps and the nucleation surface in long-term experiments. This technique has managed to fill in the gap between atomic-level observations of AFM and macroscopic data obtained by interferometry.
