Preparation, Micro-hardness Characterization on Untreated and Treated with Electric Stressed Samples on the Inorganic Tunable Laser Dye Rhodamine Doped PMMA

Effect of Load, Load dependent nature of Micro hardness measurement and Doping Effect on untreated samples and Micro hardness studies on the effect of charge due to electrical stress on the samples of pure and Rhodamine doped PMMA with different weights proportions have been carried out using Vicker's micro hardness testing for hardened networks plasticization and crystallization. Some selected samples are used to study the electrical stress, with the help of thermostat controller at different polarizing temperatures and fields in thermally stimulated depolarization current due to dipole orientation or trapping of space charges, which gives the information about uniform polarization.
