Novel inorganic phosphor luminescent materials are widely used in various optoelectronic devices such as field emission displays, plasma display panels, solid state lasers, cathode‐ray tubes, and tricolor white light emitting diodes. Structural and luminescence properties of calcium borophosphate phosphors with different Fe 3+ concentrations using solid state reaction technique have been investigated. X‐ray powder diffraction reveals that all samples exhibited a triclinic system of CaBP and lattice parameter analysis indicated the dopant ions may be substituted into the lattice position of the parent atom. The surface morphology of prepared nanophosphors is identified by SEM with EDS and TEM, which shows spherical‐like chains in an irregular spatial distribution with less agglomeration. Optical studies give the information about the site symmetry of dopant ions with host ligands.
