A unique way to contribute in the development of cutting edge technology of lighting and screen devices is to search for new or develop existing luminescent material of desired dimensions and composition suitable in technical aspect. In concern with this a promising non linear optical material; Na3La2(BO3)3 (NLBO) has a long range of transparency and exceptional stability with high damage threshold, pick up as a host material. A fine powder of polycrystalline samples of Na3La(2-x)(BO3)3:x Eu/Tb (0.01 x 0.07 wt.mol %) has been synthesized by combustion synthesis, structure and phase of compound obtained conferm by powder XRD technique; Luminescent properties of RE added NLBO were investigated under UV light. An optimum concentration of Eu3+/Tb3+ ion in NLBO was search for the highly chromatic red emission line at 613 nm with lacks of inversion symmetry and efficient green emission at 546 nm. The results obtained shows close resemblance and suitability for further development and employ them in tricolor lamps (w-LEDs) and screen printing technology.
