Abstract

Zinc strontium phosphate glasses doped with different trivalent praseodymium ion (

\Pr^{3 +}

) concentrations are presented and their photoluminescence properties are investigated upon 442 nm excitation. With the

\Pr^{3 +}

concentration decreasing, the orange emission of

\Pr^{3 +}

(

{}^{1}{D_{2}} {}^{3}{H_{J}}

) is enhanced steadily at the cost of its blue emission (

{}^{3}{P_{1,0}} {}^{3}{H_{4}}

). Monochromic orange emission of

\Pr^{3 +}

ions is obtained when the

\Pr^{3 +}

doping is reduced to 0.05 mol.%. The mechanism controlling the monochromatic characteristic of

\Pr^{3 +}

emissions is supposed to be associated with the phonon-aided nonradiative relaxation process of

\Pr^{3 +}

:
