Orangish-yellow-emitting Ca3Si2O7:Eu2+ phosphor for application in blue-light based warm-white LEDs

14 May, 2014 - 03:54

Dalton Trans., 2014, 43,7917-7923
DOI: 10.1039/C4DT00076E, PaperChien-Hao Huang, Wei-Ren Liu, Ting-Shan Chan, Yuan-Tai Lai
The crystal structure of Ca3Si2O7:Eu2+ phosphor was determined on the basis of XRD profiles using synchrotron radiation. A warm-white LED device with a low CCT has been fabricated using a blue LED chip combined with orangish-yellow-emitting Ca3Si2O7:0.015Eu2+ phosphor.

Influence of spherical assembly of copper ferrite nanoparticles on magnetic properties: orientation of magnetic easy axis

14 May, 2014 - 03:54

Dalton Trans., 2014, 43,7930-7944
DOI: 10.1039/C4DT00093E, PaperBiplab K. Chatterjee, Kaustav Bhattacharjee, Abhishek Dey, Chandan K. Ghosh, Kalyan K. Chattopadhyay
The spherical assembly of nanoparticles induces a high degree of alignment of magnetic easy axis as compared to randomly oriented nanoparticles which increases the reduced remanence ensuing straightened hysteresis loop.
