摘要: Abstract Er3+ and Yb3+ co doped GdAlO3 phosphor has been prepared by using solid state reaction method. The was characterized different instruments for knowing its exact size optical behaviour. Structural properties like crystal of the were X-ray diffraction analysis (XRD). Exact calculated electron microscopy such as transmission (TEM) results show that phosphors are in nanometer range. behaviour recording photoluminescence spectra under 980 nm excitation. shows intense emission peak green region weak peaks at blue red region. paper also deals with probable transition up-conversion mechanism phosphor.
