Preparation of xerogel films doped with R6G laser dye using spin coating technique and study the spinning parameters

الملخص EN

Spin coating technique has been applied in this work to prepared Xerogel films doped with Rhodamine 6G laser dyes.

The solid host of laser dye modifies its spectroscopic properties with respect to liquid host.

During the spin coating process the dye molecules suffer from changing their environment.

The effects of three parameters were studied here : the spinning speed, multilayer coating and formaldehyde addition.
