Abstract (first 170 chars)

The present disclosure relates to a nano-phosphor chemical composition and a method for the nano-phosphorsynthesis. The chemical composition comprises: EuBa 3B 9018 . The method comprises: mixing Eu2 O3, Y 20 3, BaCO3 , and H3BO3 to form a mixture wherein, adding excess H 3B03 to compensate for B2 03 volatilization in further steps; sintering the mixture to decompose BaCO3 and H3B0 3 slowly; and calcining the mixture with intermediate grindings and wherein, 1% mol excess H3BO3 is added to compensate for B 2 03 volatilization wherein, the mixture is sintered at 600°C for 1 hour and wherei
