The strong cross relaxation of Er3+ and Yb3+ ions in the oxyfluoride glass ceramics

Oxyfluoride glass ceramic is a new up-conversion fluorescent material with the low phonon energy just like fluoride and the good mechanical stability like oxide. In the oxyfluoride glass ceramics co-doped with Er3+ and Yb3+ ions, the red radiation is dominant while it is excited by the violet light. But in the general fluorescent material, the green radiation is dominant because the multi-phonon relaxation occurs step by step. The strong cross relaxation process of Er3+ and Yb3+ ions is mainly responsible for enhancement of the red radiation intensity in the oxyfluoride glass ceramics. The increase of the red radiation intensity of Er3+ ions by the violet light excitation shows that the rare earth ions are doped into fluoride micro-crystals which are planted into oxide host in the oxyfluoride glass ceramics.

Study on an Organic Hybrid Made from Chlorinated Polyethylene and 2,2''''-methylene-bis- (4-methyl-6-cyclohexylphenol)

The dynamic mechanical properties and miscibility of an organic hybrid made from chlorinated polyethylene (CPE) and 2, 2'-methyIene-bis-( 4-methyl-6-cyclohexylphenol) ( ZKF ) are mainly discussed in this paper. It is found that ZKF acts as an antiplasticizer in CPE matrix and has good miscibility even with large ratio in CPE /ZKF hybrids. The glass transition temperature of various CPE /ZKF hybrids determined by DSC give a good fit to Wood's equation. Bifunctional ZKF is supposed to improve the intermolecular force of CPE, and the improvement is developed when the ZKF content increases. On the other hand, the viscoelastic properties are highly improved with the addition of ZKF. TA and tanδ peak values increase when the ZKF content increase in the CPE /ZKF hybrids, the damping capacity has been improved during the glass transition of CPE /ZKF hybrids. In addition, the glass transition temperature shifts to room temperature from the low temperature with the continuous addition of ZKF to CPE.
