Purpose: Purpose of this paper, our object is solid state synthesis and investigation of structural and chemical characterization properties of Ba 3 Y(BO 3 ) 3 and Sr 3 Y 2 (BO 3 ) 4 as members of alkaline earth yttrium borates. Design/methodology/approach: In the synthesis procedure; barium carbonate, strontium carbonate, yttrium oxide and boric acid weighed an appropriate molar ratio and homogenized in an agate mortar. The mixture placed into a porcelain crucible to heat in high temperature oven at 900°C for 4 hours. After intermediate grindings, samples were cooled down to room temperature. Homogenized powders were characterized by Powder X-ray Diffractometer (XRD) to determine crystal structures. FTIR spectrum was taken to support the functional groups. Morphological properties and semi-quantitative analyse of the sample was performed by Scanning Electron Microscope/Energy dispersive (SEM/EDX). Findings: The XRD patterns of Ba 3 Y(BO 3 ) 3 and Sr 3 Y 2 (BO 3 ) 4 compounds indicate that crystallization procedure were completed successfully. The unit cell parameters of the compounds was calculated by Rietveld refinement method. In FTIR spectrum the vibrations of B-O bonds are determined via comparison to literature Research limitations/implications: Implication the synthesis method has some disadvantages such as low homogeneity, non-uniform product etc. We tried to minimize these negative aspects in our research and succeeded.

The need of new materials with desirable optical properties has become important in recent years. In particular, a need has emerged for compounds having better luminescence properties in various practical applications. The introduction of rare earth ions as activators improves the luminescence properties of the compounds considerably. Boron is one of the most abundant elements in nature. It readily combines with almost all other elements. In combination with oxygen; it forms borates comprised of various anions such as BO33−, B2O54−, etc. Apart from these simple borates, several complex compositions exist involving mixed anions as well as double metal borates, due to the three‐fold, or four‐fold coordination of borate atoms. Borates intrinsically possesses characteristics that are advantageous for optical materials, which include a wide transparency range, large electronic band gap, good thermal and chemical stability, low preparative temperature, optical stability with good nonlinear characteristics, and an exceptionally high optical damage threshold. The unique crystal structure of borates determines their enhanced ultraviolet light transparency, good nonlinearity, and relatively high resistance against laser‐induced damage. Some of these complex borates have interesting luminescence properties that are covered in this review. These include double borates containing rare earths RM3(BO3)4, pentaborates LaMgB5O10, M3R2(BO3)4, where M is an alkaline earth, mixed anion borates such as aluminoborate SrAl2B2O7, silicate‐borates such as pekovite, SrB2Si2O8, haloborates, M2B5O9X, where M is an alkaline earth and X is a halogen, phosphate borates, and MBPO5, where M is an alkaline earth. Phosphors based on these compositions find use in various applications such as fluorescence lamps, colour TVs, plasma display panels, high‐intensity discharge lamps based on xenon, optically pumped solid‐state lasers, eye‐safe lasers, and X‐ray imaging.
