In　this　work,　TiBa　glass　microspheres　doped　with　Nd3+　for　morphology-dependent　resonances　of　emission　were　designed　and　prepared.　The　emission　spectra　of　TiBa　glass　plate　and　TiBa　glass　microspheres　(45　and　13　microm　in　diameter)　under　514　nm　excitation　were　measured.　The　authors　observed　many　regularly　spaced,　sharp　peaks　in　the　emission　spectra　of　a　Nd3+-doped　glass　microsphere.　Based　on　the　Mie　scattering　theory,　the　wavelength　separation　between　the　adjacent　resonant　peaks　for　the　45　microm　sphere　was　calculated　to　be　3.0　for　810　nm.　This　value　agrees　well　with　the　observed　peak　separation　(3.1　nm),　which　indicates　the　contribution　of　the　whispering　gallery　modes.　The　emission　intensities　of　a　Nd3+-doped　TiBa　glass　microsphere　(13　microm　in　diameter)　in　the　901.69　nm　region　were　plotted　against　the　excitation　laser　power.　The　emission　intensities　of　the　microsphere　exhibit　the　linear　dependence　at　the　low　excitation　power　(＜2　mW).　The　901.69　nm　emission　intensity　of　the　microsphere　steeply　increases　at　the　excitation　power　of　2　mW,　which　can　be　ascribed　to　the　laser　operation.
