Optical tunability in Er3+ substituted Sr0.7Bi2.2Nb2O9 (BLFS) multifunctional ceramics

Conventional solid-state method has been used to produced bismuth layered ceramics of Sr0.7Bi2.2-xErxNb2O9 (SBN-xEr, x=0.0,0.4,0.6,0.8,1). Microstructure of all the samples were very dense. The structural and optical properties of the ceramics were investigated successfully. Under the excitation of...

Description
Summary:Conventional solid-state method has been used to produced bismuth layered ceramics of Sr0.7Bi2.2-xErxNb2O9 (SBN-xEr, x=0.0,0.4,0.6,0.8,1). Microstructure of all the samples were very dense. The structural and optical properties of the ceramics were investigated successfully. Under the excitation of 250 nm, Er3+ substituted Sr0.7Bi2.2Nb2O9 has four intense emission bands peaking around 424 (violet), 444 (violet), 464 (Blue), 478 (Blue). In the present work SBN, well known ferroelectric material, beside the ferroelectric property, shows remarkable optical property because of Er3+ substitution. This feature of Er3+dopedSBN sample can be good for optoelectronic-device application. This also indicates that SBN-xEr ceramics can be used for high temperature optical application.
