Quenching Glass Ceramic

For different concentrations the emission spectra and decay curves of the 4i13 2 4i15 2 emission were measured.

Quenching glass ceramic.

Ce la nd po 4 phosphate based glass ceramics are potential candidates for the hlw. Glass ceramic materials share many properties with both glasses and ceramics glass ceramics have an amorphous phase and one or more crystalline phases and are produced by a so called controlled crystallization in contrast to a spontaneous crystallization which is usually not wanted in. Quenching effect will be there on both physical and structural properties. Glass ceramics are polycrystalline materials produced through controlled crystallization of base glass.

This ultratransparency is attributed to the spatial correlation of the nanoparticles. The thermal quenching of fluorescence of ce y 3 al 5 o 12 glass ceramic yag gc phosphor was evaluated and compared with those of ce y 3 al 5 o 12 polycrystal yag pc and ce gd y 3 al 5 o 12 glass ceramic gdyag. The er concentration dependence of integrated intensity and lifetime of 4i13 2 4i15 2 emission are showed. In this work we have studied the concentration quenching in transparent glass ceramics containing er3 nayf4 nanocrystals.

The glass referenced as cel2 was prepared by a traditional melting quenching process. Summary this paper presents the results of an experimental study of heat transfer characteristics in single phase and two phase stagnation point flows pertinent to quenching of glass in the temperi. The feasibility to immobilize the hlw by monazite iron phosphate glass ceramics is discussed. With the increase of the er3 doping.

Glass ceramics with nanocrystals present a transparency higher than that expected from the theory of rayleigh scattering. Monazite iron phosphate glass ceramic wasteforms were prepared by a melt quenching process. Do micro structural properties after different rate of quenching simultaneously measure the physical properties also.
